The equations can be utilized for any motion that can be described as being either a constant velocity motion (an acceleration of 0 m/s/s) or a constant acceleration motion. They can never be used over any time period during which the acceleration is changing. Each of the kinematic equations include four variables.
Accordingly, what is constant acceleration on a graph?
The curves on the previous graph were all straight lines. A straight line is a curve with constant slope. Since slope is acceleration on a velocity-time graph, each of the objects represented on this graph is moving with a constant acceleration. Were the graphs curved, the acceleration would not have been constant.
When the velocity is constant is the acceleration 0?
By definition, acceleration means change in velocity. So if the velocity is constant, this means both speed and direction are constant. And there has to be at least one of these things changing for the velocity to change, the acceleration is zero if none of these things change and the velocity is said to be constant.
What is the motion of an object with constant acceleration?
Motion with constant acceleration. Motion with constant acceleration occurs in everyday life whenever an object is dropped: the object moves downward with the constant acceleration , under the influence of gravity. Likewise, is the body's instantaneous velocity at time .
