Time-graphs

Question 1

What are the types of graphs?

Answer 1

Displacement
Velocity
Acceleration

Question 2

Stationary on DISTANCE-time graph

Answer 2

A horizontal line on a distance-time graph means that the object is at rest (𝑣 = 0 𝑚 𝑠^(−1) ).

Question 3

Constant speed on DISTANCE-time graph

Answer 3

A straight line with a constant slope on a distance-time graph means the object in question is travelling at a constant speed.

Question 4

SPEED-time graphs - stationary

Answer 4

A straight horizontal line along the time axis shows the object is not moving (stationary).

Question 5

SPEED-time graphs – constant speed

Answer 5

A straight horizontal line at any point other than the zero line shows that the object is moving at a constant speed.

Question 6

Displacement on a DISPLACEMENT-time graph

Answer 6

Add up total distance=displacement

Question 7

Velocity on a DISPLACEMENT-time graph

Answer 7

𝑣𝑒𝑙𝑜𝑐𝑖𝑡𝑦=𝑑𝑖𝑠𝑝𝑙𝑎𝑐𝑒𝑚𝑒𝑛𝑡/𝑡𝑖𝑚𝑒

𝑣=𝑑/𝑡

Question 8

Speed on DISPLACEMENT-time graph

Answer 8

𝑠𝑝𝑒𝑒𝑑=𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒/𝑡𝑖𝑚𝑒

𝑣=𝑑/𝑡

Question 9

how to find acceleration and displacement on a VELOCITY-time graph

Answer 9

The gradient of a velocity-time graph will give the acceleration.

The area under a velocity-time graph will give the displacement
