Examples of constant velocity in the following topics:

 An object moving with constant velocity must have a constant speed in a constant direction.
 Motion with constant velocity is one of the simplest forms of motion.
 To have a constant velocity, an object must have a constant speed in a constant direction.
 If an object is moving at constant velocity, the graph of distance vs. time (x vs. t) shows the same change in position over each interval of time.
 Examine the terms for constant velocity and how they apply to acceleration



 Instantaneous velocity is the velocity of an object at a single point in time and space as calculated by the slope of the tangent line.
 A graphical representation of our motion in terms of distance vs. time, therefore, would be more variable or "curvy" rather than a straight line, indicating motion with a constant velocity as shown in .
 To calculate the speed of an object from a graph representing constant velocity, all that is needed is to find the slope of the line; this would indicate the change in distance over the change in time.
 Since our velocity is constantly changing, we can estimate velocity in different ways.
 Determine what differentiates instantaneous velocity from other ways of determining velocity





 Imagine a particle moving in a circle around a point at a constant speed.
 We recall from our study of linear velocity that a change in the direction of the velocity vector, is a change in velocity and a change in velocity is acceleration.
 Thus, while the object moves in a circle at constant speed, it undergoes constant linear acceleration to keep it moving in a circle.
 However, it's angular velocity is constant since it continually sweeps out a constant arc length per unit time.
 Constant angular velocity in a circle is known as uniform circular motion.

 A fluid in motion has a velocity, just as a solid object in motion has a velocity.
 Like the velocity of a solid, the velocity of a fluid is the rate of change of position per unit of time.
 The flow velocity vector is a function of position, and if the velocity of the fluid is not constant then it is also a function of time.
 In SI units, fluid flow velocity is expressed in terms of meters per seconds.
 The magnitude of the fluid flow velocity is the fluid flow speed.
