Q1. Newton law of motion
Ans. 
Newton's laws of motion describe the relationship between an object and the forces acting on it.
• First law: An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

• Second law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• Third law: For every action, there is an equal and opposite reactio...read more
