1. Graphical Analysis: Velocity – Time
Homework: Worksheet

2. Velocity Time Graphs
A velocity-time graph shows the instantaneous velocity of an object
At Rest = On Horizontal Axis (Zero)
Uniform Motion = Horizontal Lines
Uniform Acceleration = Sloped Lines
We can analyse vt-graphs by:
Finding Slopes = Finding Accelerations
Finding Areas Under Lines = Finding Displacements
