Motion
Describes the location of an object
What is position?
Any push or pull from one object to another.
What is force?
The measurement of the energy used to perform a task.
What is work?
A machine that takes one force and changes its direction, distance, or strength.
What is a simple machine?
The change in velocity over time for an object.
What is acceleration?
Change in position over time.
What is motionn.
A force that opposes the motion of one object moving past another.

The product of mass multiplied by velocity.
What is momentum?
A group of objects from which you can measure a position or motion.
What is a frame of reference?
When forces act on an object without changing its motion.
