Potential & Kinetic
Question | Answer |
---|---|
What is kinetic energy? | the energy an object has due to its motion |
As a roller coaster begins to move, what happens to its 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 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. |
What has an effect on potential energy? | height and mass |
What has an effect on kinetic energy? | mass and speed |
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.) |
What kind of energy is a stretched rubber band? | potential |
Potential energy ________________ as a ball rolls down a hill. | decreases |
Two forms of energy | potential and kinetic |
The faster an object moves, the ______ kinetic energy it has. | more |
___________ energy is stored energy. | potential |
Kinetic energy _______________ as a ball rolls down a hill. | increases |
Energy due to motion is _________ energy. | kinetic |
What is the Law of Conservation of Energy? | Energy is neither created nor destroyed. |
______________is the ability to cause change. | Energy |
