• Kinetic Energy: The kinetic energy of an object is the energy which it possesses due to its motion.
• Potential Energy: stored energy, the ability of an object to do work due to its position or internal structure.
• Gravitational Energy: Potential energy that is stored in the gravitational field due to gravity.

What will happen to the two different temperature spheres when dropped at same height?
Hypothesis: If you drop one ball at room temperature and one that is warmer, the one with higher temperature will bounce higher.

Trial 1 Trial 2 Trial 3 AverageRoom Temperature
0 in. 0 in. 0 in. 0 in.
Hot Water Temperature
13 in. 11 in. 15 in. 13 in.
Superball 30 in. 28 in. 27 in. 28.3 in.Conclusion: The warm ball which contained more thermal energy conserved more energy at the collision with the ground, resulting in a higher bounce.
What was the transformation of energy during the demo?

Happy and Sad Spheres: Kinetic energy and motion of dropping the ball that contains potential and gravitational energy
collision turns the energy of the drop into sound and thermal energy.
With heat: Ball absorbed thermal energy, which means it cannot absorb as much thermal energy during
collision.
Our hypothesis that the more heated spheres would bounce more was correct.

Toy Vehicle: Compression of hand on toy mechanical energy
motion friction• Spring contains stored mechanical energy.
Yo-yo: Kinetic Energy and motion when let go as it spins down, energy converts to gravitational potential energy which causes it to go back up
Balloon: Inflation of air gives pressure – stored mechanical energyreleasing balloon – motion contraction of balloon as air is lost sounds energy from release of pressure

Swing: Gravitational potential energy alike to a yoyo.
Sled riding: Potential and kinetic energy down the hill, friction causes stopping.
Strandbeests: Kinetic energy given by wind to power the motor for mechanical energy.
