Document Summary
The acceleration of an object is depend upon two variables; The net force acting upon the object. The net free is proportion to acceleration. Mass has an inverse relationship with acceleration. Greater your mass the less acceleration you will have. For every action there is an equal and opposite reaction: runner exerts force on the block, starting block exerts a force on the runner. No direct interaction (forced acting at a distance from each other. Any object released from a height will fall freely to the earth surface due to gravity. The force of gravity causes an object to accelerate towards the earth at a rate of 9. 81m/s2. M = body mass or object mass (kg) W - the body weight of an object. A reaction force is provided by the surface when one is moving. Every surface an individual interacts with has a reaction force.
