Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

b. What is the angular velocity when t = 0?

c. What is the angular velocity when t = 5 seconds?

d. What is the angular acceleration at the start of motion?

1. Given the equation below, solve for the
following.
a. Angular Velocity (in terms of t)
b. What is the angular velocity when t = 0?
c. What is the angular velocity when
seconds?
5
d. What is the angular acceleration at the start of
motion?
0 = 2t + 0.5t³

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
