Question

Which law is referred to as the law of inertia?
A. First law of motion
B. Second law of motion
C. Third law of motion
D. None of these

Answer 1

Hint:Let us first understand about Newton's laws of motion. Sir Isaac Newton, an English physicist and mathematician, first proposed Newton's laws of motion, which are relationships between forces acting on a body and its motion.

Complete answer:
Now, let us get some idea about all laws of motion.
First law of motion: Newton's first law states that whether a body is at rest or travelling in a straight line at a constant speed, it will remain at rest or continue to move in a straight line at a constant speed unless acted upon by a force. The law of inertia is the name given to this postulate.

Second law of motion: Newton's second law states that an object's acceleration is proportional to its net force and inversely proportional to its mass. An object's acceleration is determined by two factors: force and mass.

Third law of motion: According to Newton's third law, any action (force) in nature has an equal and opposite reaction. In other words, if object A exerts a force on object B, object B will exert a force on object A that is equal to and opposite to the force exerted by object A.

So, option A is correct.

Note:Newton's laws are crucial because they apply to virtually all we see in our daily lives. These laws explain how things move and stay still, such as why you don't float out of bed or fall through your house's floor. So, every time you drive anywhere, thank Newton's law of action and reaction.
