Linear Motion Graphs

 
11.2  Linear Motion Graphs
 

1. Linear motion graphs are used to present information and data regarding a motion

2. Displacement-time graph

 
Speed and Velocity
 
t (s) Explanation Velocity
\(0 - \text{t}_1\) The gradient is positive and uniform Uniform
\(\text{t}_1 - \text{t}_2\) The gradient is zero Zero
\(\text{t}_2 - \text{t}_3\) The gradient is negative and uniform

Negative and uniform 

Moving in the opposite direction

 
3. Velocity time graph

t (s) Explanation Acceleration
0-2 The velocity increases uniformly Uniform
2-4

The gradient is zero

Velocity is constant

Zero
4-6 The velocity decreases uniformly

Negative or uniformly deceleration
