The distance an object moves in an amount of time
Speed
The space and direction of an object
Velocity
A change in velocity over time
Acceleration
The ability to do work
Energy
The energy that is stored inside an object
Potential energy
The energy an object has because it is moving
Kinetic energy
The process of an object changing position over time
Motion
Force that results from the interaction of two objects in contact with each other
Contact force
The movement of energy from one object to another or the change of energy from one form to another
Energy transfer
A force which acts on an object without coming physically in contact with it
Non contact force
A principle in physics that states that energy can neither be created nor destroyed and that the total energy of a system by itself remains constant
Conservation of energy
The tendency of a moving object to keep moving in a straight line or any object to resist a change in motion
Inertia
The force of attraction between two objects due to their mass
Gravity
We use to change __________ __________ _____________
Things grow move work
Objects with potential energy are not using _________________ right now but it is stored and can be used _______________
Energy and later
The higher the object the ___________ potential energy
More
Kinetic energy does not _____________if an object moves higher or lower
Change
An objects kinetic energy depends on the odjects _________________
Speed
The objects with greater______________has more kinetic energy
Mass
__________________is the energy an object gains when work is done on it
Mechanical energy
Two forms of mechanical energy ______________ __________________
Potential energy kinetic energy
___________ is any push or pull
Force
________________________________ of an object depends on the force on the object
Acceleration
If you apply the same force to two objects of different masses the greater mass accelerates more_______________
Slowly
