400 m
2040.82 m
4.82 m
40.82 m
What unit is used to measure height?

What is the relationship between kinetic energy and velocity?
There is no relationship
If velocity changes, then kinetic energy goes up A LOT.
Velocity doesn't affect kinetic energy.
If velocity goes up, kinetic energy drops.
What is the difference between kinetic energy and potential energy.
Potential energy can only be detected in very small objects, but kinetic energy is in all objects
Kinetic energy is only present on Earth.
Kinetic energy is moving energy and potential energy is stored energy.
Potential energy can be destroyed, but kinetic energy cannot.
Find the Kinetic energy of a 60 kg object rolling down the hill with a velocity of 8 m/s. Use the formula KE= 2 1mv2
