Description Of A Toy Energy Investigation

Kinetic Energy is the energy of movement, whether it is horizontal or vertical, it’s kinetic. There is many different types of kinetic energy. There is; vibrational, rotational and translational (the movement from one location to another. IN our experiment we also have kinetic energy. The particles that move around need kinetic energy to bond because if the particles wouldn’t have kinetic energy, they wouldn’t move, then they wouldn’t be able to collide and at last there would be no chemical reaction taking place. But for a reaction to take place there has to be enough kinetic energy to overcome the bonding forces of the reactants. The minimum amount of kinetic energy need to cause a chemical reaction is called activation energy (symbol: Ea

On a larger scale, the example of a Lego made motors efficiency can relate to that of a modern day car and the efficiency / energy waste that comes from it. The internal combustion engine is an engine in which the combustion of a fossil fuel mixes with air in a chamber of the operational fluid flow circuit.

To create a mousetrap car and measure its performance. We will also see where force and energy is impacting on the performance, for example friction will impact on the cars performance as it generates heat and slows to car down thus meaning that the car may not travel as far as it should. Another force that is demonstrated in testing of the car kinetic energy, without kinetic energy the car would not travel at all.

1. When we say that something gives us “energy,” what does that mean? What is a biological definition of energy?

The use of LEGOs is an extraordinary thing, but it is shocking to see exactly how controversial a small toy can become. People of all ages have been found to enjoy this toy. Companies and organizations such as MIT and NASA have even found a use for them. The toy has become known as a child’s imagination tool and has not been exclusively used for adults. The documentary shows that adults come together to compete in competitions on who can create the greatest LEGO sculpture. Many people may not know just how big this toy is used around the world.

As the car go down it looses its potential energy because it is not at the same height anymore. As it loses the potential energy it gains kinetic energy. Kinetic energy came along because of its high speed. The mathematical equation for this is initial kinetic energy plus initial potential energy plus external work equals final kinetic energy plus final potential energy. To find work the equation is force times distance. To find power the equation is work divided by time.

In the video "Hands-On Science with Squishy Circuits" talked about how play dough that you can make at home that it can conduct electricity.

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

All toys and equipment must relevant to the child’s age and stage of development and comply with BSEN benchmarks for safety.

In science we made Rube Goldberg machines. Are machine had to have five steps. Are first first step was for a pice of cardboard out of the box and the hair dryer blew the baseball down a ramp. The second step was for the baseball to fall of the rap and hit a tennis ball to go down another ramp. The third step was the tennis ball hit a small basketball. The forth step was the basketball fall through a hoop. Then finally the fifth step was for the basketball to hit and ring the bell.

We were given groups to design and make a mousetrap powered car that will roll as far as possible. This will be measured and be put into a graph. We will make three modifications to our mousetrap car over the course of the experiment. We have a variety of different materials, including plastic, wooden wheels and a dowel, screws, mousetrap, blue tack and a piece of string. Forces were acting in a negative way and a positive way on the car. Gravity was pulling the car down to the ground. Uplift was pushing up upon the car against gravity. Drag was also known as friction, holding back the car while it was moving. Thrust was in the cars favour, pushing forward against the force drag. There were also many forms of energy being used and being wasted like heat and sound energy. Potential energy was stored in the mousetrap, propelling itself forward. Kinetic energy was also demonstrated when the car started to roll.

The mousetrap car, Versace, was tested multiple times to test how far it went. When constructing the car, the group members had different ideas, but all ideas were put into the construction of the car. The car was tested with CDs as wheels and then paper plates as wheels. Each time, when testing the car, the axle gearing had different measurements and distances. The group had finally gotten the best distance on the car. The group was also able to find the kinetic energy of the boat. Then the data from the tests were used to find the efficiency of the car. Overall, the car did very well.

The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.

The toy has uses two main energies, Kinetic and Potential. Potential energy is made by the pulling back of the car. Kinetic is made when after the car is
