Third Law of Motion: For every action, there is an equal and opposite reaction.
Force is a push or a pull, like pulling a wagon or pushing a car. Gravity is a force that attracts things to one another. Weight is a measure of how much gravity is pulling on an object.
Gravity accelerates all things equally. Which means all things speed up (accelerate) the same amount as they fall. Acceleration is the rate of change in velocity. In other words, how fast is a change in speed and/or a change in direction happening.
