P2.1.5 - Velocity Time Graphs

Question 1

What does the gradient of a graph tell you?

Answer 1

The rate of change with time

Question 2

How do you calculate acceleration from velocity-time graphs?

Answer 2

You take readings to find the change in velocity and time, before using the equation

Question 3

If the acceleration is negative, what can be assumed about the final velocity?

Answer 3

The initial velocity is larger than the final velocity

Question 4

How do you calculate the displacement in a velocity-time graph?

Answer 4

The area underneath the line of a velocity-time graph. If there is negative sections as well, find the area above the line to the baseline and take that away from the positive displacement.

Question 5

How do you calculate distance travelled in a velocity time graph?

Answer 5

You find all the area underneath the line and add it all together no matter whether it is positive or negative

Question 6

How do you calculate displacement by using the squares on a velocity-time graph?

Answer 6

Calculate the distance represented by each square and then count the squares under the line
