The ability to do work or cause change.
Energy that is stored due to an objects position or condition.
Potential energy stored in chemical bonds ex:firewood , food.
The energy of motion
A change in position with respect to a reference point.
The distance traveled per time. D/t
The speed and direction of an object.

3 ways to reduce friction
2. Separate with rolling objects
The natural force of attraction between particles of matter. The force increases with increased mass.
Newtons first law
A body remains at rest or moves with constant velocity as long as no external force acts on it.
The tendency of objects to remain in there state of motion. It depends on mass.
Newtons 2nd law
An object will accelerate in the direction of the net force. The greater the force, or the smaller the mass, the greater the acceleration. F=m times a
Newtons 3rd law
For every action there is an equal and opposite reaction.
Unit for measuring force. One kg accelerating one m/s
Any push or pull toward the center.
