Sample Questions
What is torque?
Show answer
Rotational equivalent of force
Torque is the rotational analog of force, causing angular acceleration and representing the effectiveness of a force in producing rotation.
In pure translational motion, what is true about particle velocities?
Show answer
All particles have the same velocity
In pure translation, every particle of the body moves with the same velocity at any instant of time.
What is the relationship between linear velocity and angular velocity?
Show answer
v = ωr
Linear velocity is the product of angular velocity and the radius of rotation, where r is the perpendicular distance from the axis.
What does conservation of angular momentum require?
Show answer
Total external torque is zero
When total external torque is zero, angular momentum remains constant in a system.
