State whether the following statements are true or false:
$(a)$ The product of the mass of an object and its velocity is called linear momentum.
$(b)$ Inertia is mass,and the measure of inertia is the resistance to change.
$(c)$ Force is the change in momentum.
$(a)$ The product of the mass of an object and its velocity is called linear momentum.
$(b)$ Inertia is mass,and the measure of inertia is the resistance to change.
$(c)$ Force is the change in momentum.
(A) False. Linear momentum is defined as the product of mass and velocity $(p = mv)$. The statement says mass and momentum,which is incorrect.
$(b)$ True. Inertia is an inherent property of a body related to its mass,and it represents the resistance of an object to any change in its state of motion.
$(c)$ False. Force is defined as the rate of change of momentum $(F = dp/dt)$,not just the change in momentum.
$(b)$ True. Inertia is an inherent property of a body related to its mass,and it represents the resistance of an object to any change in its state of motion.
$(c)$ False. Force is defined as the rate of change of momentum $(F = dp/dt)$,not just the change in momentum.
