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 potential energy is transformed into kinetic energy. |
At what point on a roller coaster can you measure the highest potential energy? | What kind of energy is a stretched rubber band? |
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 very bottom of the hill |
Potential energy is in the process of increasing when something is going ...... | Potential energy increases as the object is going uphill. |
Kinetic energy _______________ as a ball rolls down a hill. | increases |
Potential energy ________________ as a ball rolls down a hill. | decreases |
What has an effect on potential energy? | height and mass |
What has an effect on kinetic energy? | mass and speed |
What is the Law of Conservation of Energy? | Energy is neither created nor destroyed. |
Two forms of energy | potential and kinetic |
Kinetic energy __________ as potential energy decreases. | increases |
Kinetic energy ___________ as potential energy increases. | decreases |
What causes a pendulum to stop moving? | 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.) |
Energy due to motion is _________ energy. | kinetic |
______________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 |
