Laws of motion MCQs for NEET

Newton’s laws of motion are the fundamental laws that are used for describing the motion of the body. There are three laws of motion and they are as follows:

An object continues to be in the state of uniform motion or in the state of rest unless an external force acts on it. (Also known as the law of inertia)
Force is a product of mass and acceleration.
For every action, there is an equal and opposite reaction. (Also known as conservation of momentum)

1. MCQ: According to Newton’s first law of motion, an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by an external force. This property is known as:
a) Inertia
b) Acceleration
c) Momentum
d) Gravitation

Answer: a) Inertia

2. MCQ: Which of Newton’s laws of motion is also known as the “Law of Action and Reaction”?
a) Newton’s First Law
b) Newton’s Second Law
c) Newton’s Third Law
d) Newton’s Law of Universal Gravitation

Answer: c) Newton’s Third Law

3. MCQ: The SI unit of force is:
a) Joule
b) Newton
c) Watt
d) Kilogram

Answer: b) Newton

4. MCQ: When an object is in equilibrium, it means that:
a) It is stationary.
b) It has zero velocity.
c) The net force acting on it is zero.
d) Its mass is balanced.

Answer: c) The net force acting on it is zero.

5. MCQ: Which of the following is an example of projectile motion?
a) A ball rolling down an inclined plane.
b) A ball thrown horizontally from a height.
c) A ball attached to a string, swinging in a circular motion.
d) A ball bouncing on the ground.

Answer: b) A ball thrown horizontally from a height.
