Write T for true and F for false statements. (6 points) a. Linear momentum is conserved in both elastic and inelastic collision….. b. Kinetic energy is conserved in an inelastic collision …… c. Total energy is conserved in an inelastic collision…… d. Individual torque depends on the position of the rotating axis …. e. In opening door, force play main role rather than torque f. The normal force(N) and resultant force (F) are equal in magnitude and opposite in directions

Answer with Explanation:

a.Linear momentum is conserved in both elastic and inelastic collision.

It is true.

b.Kinetic energy is conserved in an inelastic collision.

It is false, because there is loss of kinetic energy in inelastic collision  and kinetic energy does not conserve in an inelastic collision.

c.Total energy is conserved in an inelastic collision .

Yes , it is true total energy of system is always conserved.

d.Individual torque depends on the position of the rotating axis.

It is true, because torque is the product of force with  the distance from the axis of rotation.Hence, the torque depends on the position of the rotating axis.

e.In opening door,force play main role rather torque.

It is false, because opening door is a rotation about axis therefore, torque plays main role rather than force.

f.The normal force (N) and the resultant force are equal in magnitude and opposite in directions.

It is false, because the normal force and weight are equal in magnitude and opposite in directions.
