Constant acceleration is the rate at which the velocity of an object changes over time, and remains constant throughout the entire motion. It can be represented by a straight line on a velocity-time graph.
Constant acceleration and uniform motion are similar in that the velocity of the object is changing at a constant rate. However, in uniform motion, the object is moving with a constant velocity, while in constant acceleration, the object is accelerating at a constant rate.
The equation for calculating constant acceleration is a = (v - u) / t, where a is acceleration, v is final velocity, u is initial velocity, and t is time.
Some examples of motions with constant acceleration include a car accelerating from a stop sign, a ball rolling down a ramp, and a plane taking off from a runway.
Yes, an object can have a constant acceleration and a changing velocity. This is because acceleration is the rate of change of velocity, so if the acceleration remains constant, the velocity will continue to change at a constant rate.
