Calculate change in velocity from acceleration and time.

To calculate the change in velocity from acceleration and time, we use the formula: change in velocity = acceleration × time. Acceleration is defined as the rate of change of velocity, measured in meters per second squared (m/s²), while time is measured in seconds (s). By multiplying acceleration by the time interval, we determine how much the velocity of an object has increased or decreased during that period. This calculation is essential in understanding how forces affect motion, as it allows us to quantify the effect of acceleration on an object's velocity.
