Force is an interaction between two objects which causes a change in object motion. Typically, it causes an object with mass to accelerate or decelerate. Force can also be described as a pull or push. It is a vector quantity with a direction and magnitude.
Force is directly proportional to both mass and acceleration.
Force is categorized into two types, contact and Action At A Distance. Contact forces require the two object to be in direct contact. Action At A Distance forces do not require contact and are exerted over a distance. Types of force include air resistance, applied, centripetal, elastic, electrical, electromagnetic, friction, gravitational, magnetic, nuclear, normal, pressure, spring and tension.
The SI unit of force is the Newton.
Mass is the amount or quantity of matter in an object. The more mass an object has the more resistant it is to a change in velocity(acceleration) from a force.
The kilogram is the SI unit of mass.
Acceleration is a change in velocity. If an object is speeding up or slowing down it is accelerating. Acceleration can have a negative value.
