Question

Which graph below represents how the velocity of the sphere changes over time when falling with constant acceleration?

Answer 1

Graph B represents the velocity of the sphere changes over time when falling with constant acceleration.

• Acceleration is the measure of how quickly a body's velocity varies with regard to time, and constant acceleration occurs when a body's velocity changes proportionately over a period of time, or at a constant rate. It measures in m/s2.

• It is claimed that a body has continual positive acceleration when it begins to move with an initial velocity of zero and gradually increases to a positive value over time.

• Constant positive acceleration is demonstrated by a ball falling freely in a vertical direction.
