Changing Velocity

Constant, Changing, and Average Velocity Back Kinematics Mechanics Physics Contents Index Home In this picture we consider that the car is moving through equal displacements per equal time intervals, and this is what is meant by a constant velocity.

Constant Velocity

Since the velocity function in case of constant velocity is defined as V = k, where k is any constant, the velocity graph of an object with constant velocity with respect to time will be a horizontal line, as the slope is zero.

Instant Velocity

Instantaneous velocity is the velocity of an object at a specific point in time. This means that anywhere along the timeline of an objects movement, it will have a specific... Instantaneous velocity is the velocity of an object at a specific point in time.

Mathematics of Acceleration

In other words an object whose velocity is v has an acceleration of which is read as "dv - dt", and is the rate of change of the velocity v, with respect to time. The big advantage of using calculus to solve speed and acceleration problems is that the velocity can be written as an expression, not just a fixed number, so very complex problems ...

Terminal Velocity

Terminal velocity is the highest velocity attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (F d) and the buoyancy is equal to the downward force of gravity (F G) acting on the object.
