Introduction to Force and Laws of Motion for class 9th cbse

Newton's second law of motion is

State the laws of motion for rotating bodies.

Assertion: Newton's second law of motion gives the measurement of force. Reason: According to Newton's second law of motion, force is directly proportional to the rate of change of momentum.

State Newton.s second law of motion.

Assertion : Coulomb force and gravitational force follow the same inverse-square law. Reason : Both laws are same in all aspects.

A : Newton's second law of motion gives the measurement of force. R : According to second law of motion, force is directly proportional to the rate of change of momentum.

Give qualitative definition of force on the basis of Newton's first law of motion.

State Newton's third law of motion.
