Acceleration close accelerationThe rate of change in speed (or velocity) is measured in metres per second squared. Acceleration = change of velocity ÷ time taken. is the rate of change of velocity.

It is a vector quantity, meaning it has both a magnitude and a direction. Angular velocity (ω) is defined as the rate of change of angular displacement with respect to time. It describes how fast ...

Let's start with an example. Suppose a car travels only in the x-direction ... time interval? Let's start with the definition of velocity (in one dimension): But what if I represent this as a graph?
