Energy can be transformed but cannot be got rid of. There are lots of forms of energy but chemical energy is the most common form of energy. Energy is a chemical bond that combines atoms or molecules with each other. When the new bond is formed between to atoms the energy helps the formation. The energy that helps is normally heat energy but can also be light or electrical. When the bond is broken atoms get realised as does the energy in the bond.

Examples are; car crashes, helmets, and packaging. To make car crashes less harmful scientists and engineers have designed cars differently. They have crumple zones, they take the brunt of the force, airbags, they increase the time in the force time trade off, and they have seat belts, to keep the people in place. Helmets and packaging have protective padding that increases the stability of the object and again increases the time to stop making there be less of a

The food that we eat is one example of chemical energy, which is stored in the bonds of the molecules that make up food. When we eat the food, the large molecules are broken down into smaller molecules that can be used by the cells in the body. The process of breaking down the food and using it by our cells is called respiration. During this process the chemical energy is converted to heat, kinetic energy and other forms of chemical energy (like the one stored in the fat cells in our body).

One example of how this “Big Idea” impacts me is while playing lacrosse. One way this idea impacts me in lacrosse is when I am clearing the ball (I’m a goalie). When I bring my stick back to make a clear, the ball has potential energy due to its position in my stick. When I then proceed to throw the ball, the ball has kinetic energy because of it’s motion and gravity’s effects on it. Another example of how this “Big Idea” impacts me while playing lacrosse is while I’m running back to the goal after going for a long shot (where a player takes a shot, misses the goal, and then whoever is closest to the ball when it goes out gets possession). I have potential energy when I am leaning in the direction that I am about to start running to net, and I have kinetic energy when I then proceed to make a flying leap in front of the goal in an attempt to save the ball (I usually end up falling, but it has worked a few times). Finally, one last example of how this “Big Idea” impacts me is when I am longboarding. An example of kinetic energy when I am longboarding is when I am longboarding down a hill. My constantly increasing momentum and the trajectory of my body and board give me a lot of energy, and more than it would be if it was just my board going down the hill because my body has mass. An example of potential energy while longboarding is when I am holding my longboard with my foot on a hill so it doesn 't roll away. The longboard has

In this lab, we were applying Newton’s laws of force on a moving object. In this

For this assignment I suppose to visit the California Science Center specially the space shuttle. When I arrived there, I was bust and I told my self that I want to go to the space shuttle then I leave directly. However, the ‘s information, I notice that physics discover a big part in the life.

One Hungarian physicist once remarked in the course of writing a textbook that although he would often be referring to the motions and collisions of billiard balls to illustrate the laws of mechanics, he has neither see nor played this game and his knowledge of it was derived entirely from the study of physics books. (Barrow 21)

In the essay it will include; how distractions can affect your reaction time. How the braking distance is affected by speed. What the design of a vehicle and road conditions, can have an impact on a pedestrian. How the speed affects the occupants, if the car were to collide with a rigid object. And what design features are being put in place to minimise fatalities in car accidents.

Paolini brilliantly incorporated science, especially Physics, into his world. In fact, all magic is based on it. Any action done by magical means requires as much energy as if done by mundane means. The first rule of magic. Sounds like the law of conservation of energy. It taught me at least one thing: there are no easy ways or shortcuts in life. Determination and persistence are the key components of any success. Inheritance cycle ignited my interest in Physics and Sustainable

When something gives us energy, it supplies our bodies with materials (carbohydrates) that serve as fuel which is needed to carry out cell activities so that we can do work.

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the object’s mass. (3) For every action, there is an equal and opposite reaction. The first law means that there is a natural tendency of objects to continue what they were already doing. All objects resist changes in their state of motion, if the absence of an unbalanced force occurs, an object in motion will stay in the same state of motion. The second law, means that the heavier the object is, the more force it requires to move the same distance as lighter objects. This can be expressed through a mathematical equation, F= M A. The third law, means that for every force there is a reaction force that is equal in size, but opposite in direction. This means that whenever an object pushes another object, it gets pushed back in the opposite direction equally as

Our unit for the month of March is “How Things Move.” Throughout this unit, the children will explore how people can move their bodies and then use this knowledge to investigate how objects move. The children will begin this unit by first exploring how their own bodies move which will provide them with an experiential frame of reference for understanding how non-living things move. Once they have experienced activities that involve moving their own bodies, they will explore the motion of inanimate objects. In the coming weeks, we will talk about gravity as a force that makes objects move and explore how pushes and pulls affect how objects move. As the children participate in the different activities from this unit, they will achieve the following learning goals; in science, they will make predictions, test predictions and compare predictions. They will also be able to describe the effects of common forces on objects. In literacy, they will use descriptive language in conversations to talk about what has been seen and done. In math, they will use the language of spatial relationships to describe the position of objects. They

Every food that is alive has a vibrational frequency. That means it has an electrical charge to it. I don’t mean electricity light bulb charge (though that is possible) but I mean the energy for all the cells to stay alive. Plants, fruits and vegetables have a frequency of energy. Energy is measured in several ways. One of them is megahertz, and just like your electricity meter outside your house can measure the electricity you use, they have also measured how much electricity certain plants, fruits and vegetables have. Organs in your body consume this energy. For example your brain being the highest consumer of energy in your body, acquires approximately 220 megahertz of energy per hour. If you were to eat chocolate cake all day, that has the vibrational energy of about 4

Just about everything you do from moving to eating to listening to music involves physics. Now that I have really explored them I think it is hard to go about our day and not do something that involves physics. Some of the things I will talk about are getting out of bed, the eye and how eye glasses help a person see better, speakers, the Frisbee, sailing, and the pulleys I use to get my jeep unstuck in the mud when I ride in the woods.

    What I have learned about physics is that this subject is the study of the physical properties that surround us. Physics is how things move and what makes them move. For example, measurements such as velocity and acceleration and how they are used in physics is a major piece of the class. Also, physicists study the forces of gravity, electrical currents, and other numerous forces that hold everything together. Physics is also the study of very large things and very small things. Scientists study the stars, planets, and all other galaxies made up of matter. They also study the smaller pieces of matter such as atoms and electrons. During this year, I have learned the study of sound, light, and waves. We also studied the energy, heat, and radioactivity amongst objects. Physics not only helps us understand how objects move, but also how they change form, go from hot to cold, and what they are made of. One example of what we learned this year is the motion of an object. Motion can be portrayed as using displacement, distance, velocity, acceleration, time, and speed. We had focused on the lesson of Newton's first law: an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an outside force.
