Study Notes
Energy Forms and Kinetic Energy
- A soccer ball rolling across a flat field has kinetic energy due to its motion and potential energy due to its mass and height above the ground.
Factors Affecting Kinetic Energy
- The mass of an object and its velocity are the two factors that affect its kinetic energy.
Energy Forms in a Roller Coaster
-
At the top of the first hill, the roller coaster has potential energy due to its height and kinetic energy due to its initial motion.
-
At the bottom of the third hill, the roller coaster has kinetic energy due to its high velocity and potential energy has been converted to kinetic energy.
