... In a nutshell: Law 1: An object’s velocity doesn’t change unless acted upon by a net force. Law 2: The acceleration of an object upon which a force is acting depends on the amount of net force being applied and on the mass of the object. Law 3: For every force, there is an equal and opposite ...
