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.

Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) …

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.

Worked example of calculating displacement from time and velocity. Learn how velocity, time, and direction factor into calculating displacement. Understand the importance of unit conversion in these …

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 …

Displacement is the theoretical amount traveled. Velocity is the rate in which the object changes its position. First find the displacement, then divide it by the time to get your velocity.

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

So dividing the x component by some value, or perhaps constraining the angular velocity to a reasonable range, could really help. Here’s the entire update() method with these tweaks added.
