Question | Answer |
---|---|
What is potential energy? | the energy stored in an object because of its position |
As a roller coaster begins to move, what happens to its energy? | the energy an object has due to its motion |
At what point on a roller coaster can you measure the highest potential energy? | The potential energy is transformed into kinetic energy. |
A ball rolls down a hill and then stops at the top of the next hill. Where is the kinetic energy the greatest? | At the top of the largest hill because it has the most potential to cause change |
Potential energy is in the process of increasing when something is going ...... | At the very bottom of the hill |
Kinetic energy _______________ as a ball rolls down a hill. | Potential energy increases as the object is going uphill. |
Potential energy ________________ as a ball rolls down a hill | increases |
What has an effect on potential energy? | decreases |
height and mass What has an effect on kinetic energy? | height and mass |
What is the Law of Conservation of Energy? | mass and speed |
Two forms of energy | Energy is neither created nor destroyed. |
Kinetic energy __________ as potential energy decreases. | potential and kinetic |
Kinetic energy ___________ as potential energy increases. | increases |
What causes a pendulum to stop moving? | decreases |
Energy due to motion is _________ energy. | Air resistance creates friction that slows the pendulum down until it stops. This causes the gravitational energy to become potential energy. No energy is destroyed. (This is the Law of Conservation of Energy.) |
______________ is the ability to cause change. | energy |
The faster an object moves, the ______ kinetic energy it has. | more |
___________ energy is stored energy. | potential |
What kind of energy is a stretched rubber band? | potential |
