Average Velocity

To calculate the other physical quantities in kinematics, we must introduce the time variable. The time variable allows us not only to state the position of the object during its motion, but also how fast it is moving. The speed at which an object is moving is given by the rate at which the position changes with time. For each position x

The average velocity tells how fast an object is moving over time and is defined as the total displacement between two points divided by the time taken to travel between them.

For example, if p₁ and p₂ are the positions of an object at time t₁ and t₂, then ave...
