2. Speed and Velocity

Instantaneous Speed:

Instantaneous speed is a speed of a particular instance of time.

Uniform Speed:

Equal distances covered in equal intervals of time gives us uniform speed.

*Remember if an object is under circular motion, its speed is uniform but the velocity is changing. It is because the direction of motion keeps changing when the object is moving.

Difference Between Velocity And Speed:

Velocity has magnitude and direction while speed has magnitude only.
