Objects can move in a variety of different ways – they can go in a straight line, turn, speed up, slow down, even stop and start again.

Watch the video below and think about the types of motion that are occurring. Write a few notes about when you notice each of the following types of motion in the video:

• Speeding up
• Slowing down
• Moving at a constant rate

Scientists describe motion using words like displacement, velocity, and acceleration with graphs and equations.

In physics, three possible types of motion are considered: constant velocity, constant acceleration, and variable acceleration. In this lesson, you will learn about displacement, constant velocity, and constant acceleration motion. These types of motion can be studied in high school with a basic understanding of algebra and geometry.
