Force and Motion
Forces are a push or pull on an object. Forces can be due to phenomena such as gravity, magnetism, or anything that might cause a mass to accelerate. In physics, a force is any interaction that, when unopposed, will change the motion of an object.

Momentum is determined by the speed of an object and the direction it is traveling (velocity) of an object and the object’s mass. This momentum is conserved as long as there are no new objects added to the system.
- Momentum is a vector quantity.
- Momentum is mass in motion, whereas forces are pushes or pulls applied to an object or mass.
- Momentum is conserved in a collision.
