Laws of Motion

Q2. A force can change the motion of an object.

Q3. Mass changes with location, while weight does not.

Q4. Doubling the distance between two bodies makes gravitational force four times.

Q5. The SI unit of acceleration due to gravity is m s⁻¹.

Q6. Torque is the product of force and perpendicular distance.

Q7. Mass and weight are exactly the same physical quantity.

Q8. Momentum of a body is independent of its mass.

Q9. Impulse is equal to change in momentum.

Q10. Increasing collision time increases the average impact force.
