3. Mass is a measure of the inertia of an object.
4.if an Object stays at rest, there Is no force acting on it.
5. Rocket launching is an example of third law of motion.
6. Gravitational force depends on mass and distance of the two objects.
7. Magnetic and gravitational forces are examples of non-contact forces.
8. The magnitude of the force of gravity on an object is called the object’s weight.
9. In first law of motion, a moving object that is not acted upon by a net force will accelerate.
10. According to the second law of motion acceleration of an object and is inversely proportional to the net force and directly proportional to its mass.
