Graphs

Question 1

Distance - time graphs

Answer 1

Distance = y - axis
Time = x - axis
Finding the speed = difference in distance between points/difference in time
Object is stationary = horizontal line

Question 2

Velocity - time graphs

Answer 2

Velocity (m/s) = y - axis
Time (s) = x - axis
Finding the distance = area under the line (use shape area)
Object is stationary = graph line returns to 0

Question 3

Describing a curve on a velocity - time graph

Answer 3

• there is a resultant force
• so it accelerates
• air resistance increases as speed increase
