Motion graphs

Question 1

What is the difference between a distance-time graph and a displacement-time graph?

Answer 1

displacement is distance from a certain point

Question 2

Describe the motion of a ball being thrown vertically in relation to displacement

Answer 2

immediately after being thrown the gradient is large so it has a large velocity

as the ball rises, it velocity decreases so gradient decreases

at its maximum height, its velocity is zero and the gradient is zero

as the ball descents, its velocity becomes increasingly negative

Question 3

What does the gradient of the line represent in a velocity-time graph?

Answer 3

acceleration

Question 4

What does the area under the line represent in the velocity-time graph?

Answer 4

displacement of the object from the starting position
