Displacement-Time graphs

Question 1

Identify the following forms of motion on an x-t graph: uniform velocity (including zero), acceleration (positive and negative)

Answer 1

• Uniform velocity is a straight line
• Acceleration is the gradient of the graph

Question 2

The gradient of an x-t graph gives:

Answer 2

• The acceleration

Question 3

Appreciate the potential differences between an 𝑥 − 𝑡 graph and a simple distance-time graph.

Answer 3

• X-t graph focuses on direction
• A straight line may mean different thigns
