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 kinematic …

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 change your …

This means for projectile motion, the starting velocity in the x-direction will be the same as the final velocity in the x-direction, while the starting and ending velocities in the y-direction will be different …

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.

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.

Intro to vectors and scalars Average speed & velocity (with examples) Average velocity and speed in one direction: word problems Average velocity and speed with direction changes: word problems …

Let’s explore how to calculate the position and velocity of a system’s center of mass. We’ll see how the motion of a system's center of mass is related to momentum and how it can be used to model a …

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 speed in these …

How do we calculate the velocity of one object as seen by another object? In this video, we will intuitively figure out how to calculate relative velocities with some examples.
