What is constant acceleration equal to?
What is constant acceleration equal to? If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, […]
