Answer 1

ʜᴇʏᴀ....!!!

Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer 2

Answer:

1. A particle remain at rest or moves in straight line with a constant speed unless it is compelled to change that state by an external unbalanced force. 1st law gives the definition of inertia. Ex; When a bus starts suddenly, the passenger fall backward.
2. The rate of change of momentum of a particle is directly proportional to the force acting on it and takes place in the direction of applied force. Ex; When we apply force on a body it tends to achieve some acceleration. F=ma.
3. To each & every action there is an equal and opposite reaction. Ex; When a rubber ball is strucked against a wall, the ball bounce back.
