In our experiment the question we were trying to answer was “Does a physical change, change the mass of an object”. This means that when you take a tablet or clay and you crush it or alter the shape of it and it does not weigh the same after then the weight of the object did change and that would answer your question. When a physical change occurs it is not forming a new object it is just changing the way it looks or changing a solid to a liquid such as ice melting. During our experiment we took

to another, but the total amount of energy never changes. In this lab, roller coasters were constructed out of foam tubes to show the transformations of energy. Other variables that were identified during the lab were the speed of the coaster, the forces of motion and potential and kinetic energy. In this lab, a roller coaster was constructed using 3 - 1.83 meter foam tubes as a track (totaling in 5.49 meters), one marble (any type), masking tape, a stopwatch and a meter stick. In the roller coaster

Elastigirl is a very well known superhero in the movie, The Incredibles. She has the flexibility superpower, and she can stretch any part of her body up to 100' (30 m) and to a minimum thickness of 1 mm, and mold it into several shapes and sizes as well. Elastigirl also has the superpower of invulnerability, meaning she can withstand large amounts of pain and discomfort. It is mind boggling to think about how Elastigirl has these superpowers that she possesses. The only answer to this is biology

Newton's Second law of motion proves that there is a relationship between Weight and Mass. Newton's second law of motion says that F(Force)=ma (mass x acceleration). Weight is a Force. It is due to gravitational force. Mass is measured in Kg or g and Weight is measured in Newtons as it is a Force. For example if you push a little boy on a swing with the same force you push an older man on a swing with the little boy will go higher. This is because he has less mass than the older man.

direction. The second objective was to win the mousetrap car competition against the other teams in the EG1003 class. The car came in second place in the competition. During the competition, the mousetrap acted as the propulsion source, which created force in order to move the vehicle. Similarly, in real-world applications, the internal combustion engines in automobiles release the fuel combustion into energy for movement once the combustion gases push the piston, allowing the rotation of the crankshaft

of the weight onto the front foot, a bent elbow to begin with, then the arm straightened out with wrist cocked, thus the force of the arm is being put into the wrist, hands, and then the racket. Extension of the arm and stepping forward means the muscles will be at optimum stretch (quadriceps, Biceps) allowing for optimum force. The racket then generates a large amount of force (from the range of motion) when contacting the ball. - Transfer and Conservation of Momentum - Momentum is conserved throughout

Purpose and Background: We used an air track and varying amounts of mass to determine the drag coefficient on an object. We used the equation FD=1/2CDpAV^2 to determine the drag coefficient. We also used FD=ma to determine FD, and we used V^2=Vi^2+2a(x-xi) to determine velocity. Since the cross-sectional area is remaining constant, the drag coefficient should also remain constant. We will measure the acceleration of the object and use that to determine velocity and drag coefficient. We will do this

momentum to be correct, as the net force of a marble caused the acceleration of another marble. The distance the marble travelled depended on the net force, which in this experiment changed due to the different masses. When the mass of the marble was lighter, it had a decreased net force, causing it to have less momentum, as when it collided with the stationary marble the distance travelled was only 3.5cm. The marble containing the heaviest mass had a greater net force and impulse, affecting the change

much as they make their way through the loop. There is a large radius being kept through the bottom half of the loop in which it reduces the acceleration and weight on passengers. The straight line in a vertical loop creates a thrilling acceleration force which also keeps passengers in their seats. This is demonstrated by the direction of a passenger’s initial velocity pointing straight towards at the same angle as it reaches to the top of a roller coaster. As a car approaches a loop, the track guides

Just like humans, dog feel stress as well. Going through stressful situations, like moving to a new home or getting a new addition to the family, can leave your dog feeling stressed out. Being stressed out is not an ideal condition for your dog. Here are three natural methods you can use to sooth your stressed out dog and help them make it through tough situations. #1 Shen Calmer A shen calmar is based on traditional Chinese medicine. Within traditional Chinese medicine, the spirit is referred
