DIFFERENCE BETWEEN LINEAR DISPLACEMENT AND ANGULAR DISPLACEMENT

Linear displacement refers to the change in position of an object along a straight path, typically measured in units such as centimeters (cm), meters (m), or kilometers (km). The SI (CGS) unit for linear displacement is the centimeter (cm).

Angular displacement, on the other hand, refers to the change in orientation or angle of an object as it moves around a circular path. It is measured in units such as radians (rad) or degrees (°). The SI (CGS) unit for angular displacement is the radian (rad).

Formula:

1. Linear displacement (d) = final position - initial position

2. Angular displacement (θ) = final angle - initial angle

Example:

Let's say a car travels from an initial position of 10 cm to a final position of 30 cm. The linear displacement would be:

Linear displacement (d) = 30 cm - 10 cm = 20 cm

Now, let's consider a wheel rotating from an initial angle of 45° to a final angle of 135°. The angular displacement would be:

Angular displacement (θ) = 135° - 45° = 90°

Both linear and angular displacement describe changes in position, but in different contexts - linear for straight-line motion and angular for rotational motion.
