Speed is the rate of change of distance over time, and is calculated by dividing the distance travelled by time taken. Formula: Speed = Distance / Time
Velocity is the rate of change of displacement over time, and is calculated by dividing the displacement travelled by time taken. Formula: Velocity = Displacement / Time
Acceleration is the rate of change of velocity over time, and is calculated by dividing the change in velocity by time taken. Formula: Acceleration = Change in Velocity / Time
Speed is a scalar quantity, meaning it has only magnitude and no direction.
Velocity is a vector quantity, meaning it has both magnitude and direction.
Acceleration is also a vector quantity, and it is the rate of change of velocity with respect to time.
Acceleration can be positive (speeding up) or negative (slowing down).
