What is a Force?

Video Summary

Force is a push or pull upon an object. It is not just humans pushing or pulling. Even when an object is stationary, there are forces acting on it. For an object to move, there has to be some net force. If the object is moving at uniform velocity, the net force acting on it is zero.
