Work
work is the transfer of energy that occurs when a force causes an object to move in the direction of that force.
Kinetic Energy
energy an object has because it is moving.
Potential Energy
Potential energy is the energy an object has because of its position or condition
PE =
mgh
KE =
1/2mv²
W =
F x d, ▲KE (1/2mvf²-1/2mvfi²)
Potential Energy relative to Kinetic Energy
PEi + KEi = PEf KEf
