Rules Of Graphs

Question 1

How do you find displacement (d-t)

Answer 1

Read off graph (with sign)

Question 2

How do you find distance (d-t)

Answer 2

Add up all distances up to the point (without sign)

Question 3

How do you find velocity (d-t)

Answer 3

Velocity = slope of the line at the point
(With sign)

Question 4

How do you find speed (d-t)

Answer 4

Speed = slope of the line at the point
(Without sign)

Question 5

How do you find average velocity? (d-t)

Answer 5

Draw a line from start to finish and find it’s slope (with sign)

Question 6

How do you find the average speed? (d-t)

Answer 6

Find the distance travelled and divide it by time (without sign)

Question 7

Can you find acceleration on d-t graph?

Answer 7

No.

Question 8

How do you find displacement? (v-t)

Answer 8

Displacement = area between line and horizontal axis (with sign)

Question 9

How do you find distance? (v-t)

Answer 9

Distance = area between line and horizontal axis (without sign)

Question 10

How do you find velocity? (v-t)

Answer 10

Read it directly off the graph (with sign)

Question 11

How do you find speed? (v-t)

Answer 11

Read it directly off graph (without sign)

Question 12

How do you find average velocity? (v-t)

Answer 12

Find displacement (area) then divide it by time (with sign)

Question 13

How do you find average speed? (v-t)

Answer 13

Divide distance (area) by time (without sign)

Question 14

How do you find acceleration? (v-t)

Answer 14

Slope of line at the point = acceleration (with sign)

Question 15

How do you find average acceleration? (v-t)

Answer 15

Draw a straight line between initial and final points then find slope of line (with sign)

Question 16

What is acceleration always?

Answer 16

A vector. Always use sign when calculating acceleration

Question 17

What does slope equal on a d-t graph?

Answer 17

Velocity

Question 18

What does the slope equal on a v-t graph?

Answer 18

Acceleration
