1. NEWTON’S THREE LAWS

7. Magician And Inertia

10. Newton’s Second Law of Motion
Newton’s second law is the relation between acceleration and force. Acceleration is proportional to force and inversely proportional to mass.

11. 4Weight – the Force of Gravity; and the Normal Force
Weight is the force exerted on an object by gravity. Close to the surface of the Earth, where the gravitational force is nearly constant, the weight is:
What do the bold letters mean?
On Earth a mass of 1.0 kg weighs about 2.2 lb
