What are Newton’s laws of motion?

1.	What are Newton’s laws of motion?
Answer» (1) Newton’s first law of motion: An object continues to remain at rest or in a state of uniform motion along a straight line unless an external unbalanced force acts on it. (2) Newton’s second law of motion: The rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of the force. (3) Newton’s third law of motion: Every action force has an equal and opposite reaction force that acts simultaneously. [Note: Equal in magnitude and opposite in direction.]

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
