PE
This is the amount of stored energy in an object based on it's height or _________ = m * g * h
PE (potential energy)
This is the amount of energy an object has while moving or _______ = 1/2*m*v^2
KE (Kinetic Energy)
The unit PE is measured in is....
Joules!
KE is measured in....
Joules
If you double an object's height, what happens to your PE?
It doubles as well!
If I double an objects velocity, I do this to its kinetic energy.
Quadruple Kinetic Energy- KE becomes 4 times as big.
Before an object begins to move, the Total Mechanical Energy (PE + KE) an object has is equal to its_______.
PE!
A pendulum is swinging back and forth. As the pendulum moves from its lowest point to its highest point, its energy transfers from Kinetic Energy to this type of energy.
PE
An object moves down a ramp without friction. The object loses potential energy and gains this type of energy.
KE
A hot wheels car is moving down a ramp with friction. The potential energy the car started with is now these types of energy.
