You know that a large displacement in a small amount of time means a large velocity and that velocity has units of distance divided by time, such as miles per hour or kilometers per hour.

Learn how to find an object’s instantaneous speed or velocity in three ways - by using calculus, by looking at the slope of a given point on a graph of an object’s rate vs. time, or by using …

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.

Learn how to interpret the motion of an object represented on a velocity vs. time graph.

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or …

Velocity v measures the amount of displacement per time. It is a vector and has a direction (Figure 1). The same letter v is often used to represent the speed (sometimes called linear …

This equation can be derived by combining two equations for average velocity. Average velocity is defined as displacement divided by the time during which that displacement occurred:

There's multiple ways to approach these types of questions, but the big takeaway here is one, how we calculated angular velocity, and then how we can relate angular velocity to speed.

Now one thing to keep in mind when we're thinking about velocity as a function of time is that velocity and speed are two different things. Speed, speed, let me write it over here.

For example, to describe the velocity of an object, we need to know both how fast the object is moving and in which direction it goes. For example, a box can have a velocity of 5 m/s in a …
