Engineering Physics

Question 1

Angular Displacement

Answer 1

The change in angle through which a body rotates relative to a fixed point.

Question 2

Angular Velocity

Answer 2

The rate of change of angular displacement with respect to time

Question 3

Angular Acceleration

Answer 3

The rate of change of angular velocity with respect to time

Question 4

Torque

Answer 4

The change in rotational motion due to a turning force

Question 5

Inertia

Answer 5

The resistance to a change in motion

Question 6

Moment of Inertia

Answer 6

The resistance to a change of rotational motion, depending on the distribution of mass around a chosen axis of rotation

Question 7

Conservation of Angular Momentum

Answer 7

The angular momentum of a system always remains constant, unless a net torque is acting on the system

Question 8

Angular Impulse

Answer 8

An average resultant torque tau acting for a time increment t produces a change in angular momentum increment L
