... Newton's Laws . ... Mass . ... The most familiar force is weight, the downward force on an object due to gravity. ... In the absence of opposing forces, if a force does act on an object at rest or moving at constant speed, it accelerates in the direction of the force. ... By Newton's second law, the acceleration a of an object is proportional to the force F acting on it and inversely proportional to its mass m. Expressing F in newtons we now get a --for any acceleration, not just for free fall--as ....
