FAQs

Question: What is the difference between angular velocity and linear velocity?
Answer: Angular velocity refers to the rate of change of angular displacement, while linear velocity is the rate of change of linear displacement. They are related through the radius of the circular path.

Question: How is torque calculated?
Answer: Torque is calculated using the formula τ = r × F, where τ is torque, r is the distance from the pivot point to the point of force application, and F is the force applied.
