In summary, the equation Vav=(Vi+Vf)/2 is not only valid for constant acceleration, but can also be true for variable acceleration. This is because any velocity function with the same amount of area under the curve as a constant acceleration function will also yield the same average velocity.

Average velocity is the overall displacement of an object divided by the total time it took to travel that distance. Constant acceleration, on the other hand, is the rate at which an object's velocity changes over time. While average velocity is a measure of the overall displacement, constant acceleration is a measure of the change in velocity.

Average velocity is calculated by dividing the total displacement of an object by the total time it took to travel that distance. The formula for average velocity is: average velocity = total displacement / total time.

Velocity and acceleration are related in that acceleration is the rate of change of velocity over time. This means that any change in an object's velocity, whether it is speeding up, slowing down, or changing direction, is considered acceleration.

Yes, an object can have a constant acceleration but varying velocity. This can occur when the object is moving at a constant rate but in different directions, such as in circular motion. In this case, although the object's acceleration remains constant, its velocity continuously changes due to the change in direction.

Constant acceleration causes an object to change its velocity by the same amount every second. This means that the object's speed will either increase or decrease at a constant rate. This type of motion is known as uniformly accelerated motion and follows the equations of motion: v = u + at, s = ut + 1/2at², and v² = u² + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration, t is the time, and s is the displacement.
