Newton's Laws of Motion

Assertion: We should always wear a seat belt while travelling in a car.

Reason: Seat belt prevents us from falling forward due to inertia when sudden brakes are applied.

Name the physical quantity which gives a quantitative measure of the inertia of a body.

(Choose from: Temperature/Mass)

Which body offers more inertia - heavier body or lighter body?

Which of the following is the correct relation?

Force is inversely proportional to the acceleration of the body.

An object of mass $4 \mathrm{kg}$ is moving with a constant velocity of $4 \mathrm{m} {\mathrm{s}}^{-1}$ on a frictionless table. The force required to keep the object moving with the same velocity is
