What is Difference Between Uniform Acceleration and Uniform Velocity?

Here is a clear explanation of the difference between uniform acceleration and uniform velocity:

Uniform Velocity

• Definition: An object is said to be moving with uniform velocity when it covers equal distances in equal intervals of time, and both its speed and direction remain unchanged.
• Characteristics:
  • The velocity does not change with time.
  • No acceleration is present; the rate of change of velocity is zero.
  • The object's motion is a straight line at constant speed.
• Example: A car moving in a straight line at a constant speed of 60km/h.

Uniform Acceleration

• Definition: An object is said to be under uniform acceleration if its velocity changes by equal amounts in equal intervals of time, either increasing or decreasing at a constant rate.
• Characteristics:
  • The acceleration remains constant throughout the motion.
  • The velocity changes (increases or decreases) at the same rate each second.
  • The object may speed up or slow down, but the change in velocity per unit time is the same.
• Example: A ball dropped from rest accelerates downward at a constant rate due to gravity (approximately 9.8m/s² downward).
