Which law of motion gives the measure of force ?

Newton's first law of motion defines force and Newton's second law of motion gives us a measure of force. Comment.

Assertion : Newton’s third law of motion is applicable only when bodies are in motion. Reason : Newton’s third law applies to all types of forces, e.g. gravitational, electric or magnetic forces etc.

State Newton's Second law of motion. Derive a mathematical formula to calculate force if mass remains constant. Prove that it contains Newton's first law.

Explain Newton s laws of motion and show that (i) Newton s first law of motion defines force and (ii) Newton s second law of motion gives us the measure of force.

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.
