### UNIT1:Graphs of linear motion

**Key Unit Competence:**By the end of this unit, the learner should be able to plot and analyze the graphs of linear motion.Dear students,

You are welcome to learn this unit Graphs of linear motion of S3 Physics

## Learning objectives

By the end of this unit, the learner should be able specifically to

• Describe graphs of uniform rectilinear motion.

• Plot distance - time graphs and velocity- time graphs.

• Identify uniform velocity and non-uniform velocity from displacement-time graphs.

• Identify uniform acceleration and non-uniform acceleration from velocity–time graphs.

• Explain why the slope of a distance-time graph gives speed.

• Explain why the slope of a distance-time gives speed.

- Appreciate that the slope of distance -time graph gives velocity while the slope of velocity-time graph gives acceleration.

• Appreciate that linear motion can be represented using graphs.
