Torque

Newton-meter

### What is the condition for a body to be in equilibrium?

The net torque acting on it must be zero

### What is the difference between centrifugal and centripetal force?

Centrifugal force is a real force while centripetal force is fictitious

### How is force quantitatively defined when applied to a body?

$F = ma$

### Which term describes the rate of change in linear momentum of a body?

$\frac{dp}{dt}$

### What is the difference between linear and rotational motion?

Linear motion involves movement in a straight path, while rotational motion involves movement in a circular path.

Torque

### In which scenario does a body experience rotational motion?

When a force is applied to a body pivoted at a point.

### What determines the turning effect of a force on a body?

The magnitude of the applied force and the perpendicular distance of its line of action

### How does torque relate to the direction of rotation?

Torque can cause either clockwise or counterclockwise rotation.

### What are the two factors affecting the turning effect of a force on a body?

Magnitude of the force applied and perpendicular distance of its line of action
