Displacement Time Graphs

Question 1

In a Displacement-Time Graph which axis is displacement and which is time?

Answer 1

Displacement is plotted on the y-axis and time on x-axis.

Question 2

How do you calculate acceleration from a Displacement/time graph?

Answer 2

Create two tangents at 0 displacement and the final displacement find dy/dx to calculate the gradient and that value is your velocity. from this the change in velocity/change in time is the acceleration.

Question 3

How do you find the velocity of a Displacement/Time graph?

Answer 3

Change in displacement/ time taken
Create a tangent at the point you need to measure and find dy/dx to calculate the gradient and that value is your velocity.
