Speed Velocity and Acceleration Practice

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Velocity is the speed of an object in a specific direction. It is a vector quantity.

Acceleration is the rate of change of velocity per unit of time. It can be positive (speeding up) or negative (slowing down).

Speed = Distance / Time.

The standard unit of speed is meters per second (m/s).

Speed is a scalar quantity (magnitude only), while Velocity is a vector quantity (magnitude and direction).

A car traveling at 60 km/h on a straight road without changing speed.

A car increasing its speed from 20 m/s to 40 m/s in 5 seconds.

Acceleration = (Final Velocity - Initial Velocity) / Time.

The standard unit of acceleration is meters per second squared (m/s²).
