Question

define three laws of motion and give one example for each​

Answer 1

Answer:

In 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 it's mass times it's acceleration.in the third law when two object interact they apply forces to each other of equal magnitude and opposite direction..

Explanation:

hope it's helpful ☺️

Answer 2

NEWTON'S LAWS OF MOTION -

• Explains the forces acting on the body and the motion of the body.

1. Law of Inertia

• If a body is at rest it will remain at rest until and unless an external force acts on the body.
• If a body is in motion on a straight line it will remain in motion until and unless an external force is applied to the body.
• Example - If a ball is rolled, it will not stop until and unless frictional force stops it.

2. Momentum

• Force exerted on the body in motion is directly proportional to the acceleration of the body.

• $F \alpha a$ or $F = ma$

• Force exerted on the body is equal to the momentum of the body with the time rate of change.
• Example - Riding of the bicycle by pending applies force and by virtue of this force, the cycle moves forward.

3. Law of action and reaction

• When two bodies interact with each other, they exert equal and opposite force.
• The law explains static equilibrium by balancing the forces.
• Example - An object resting on the table exerts a downward force equal to weight to the book.
