Velocity Time Graphs and Acceleration

Question 1

how do you calculate the distance travelled form a speed time graph?

Answer 1

area under the graph

Question 2

An object moving forwards corresponds to positive velocity on a velocity time graph. What would the object having negative velocity represent?

Answer 2

object moving backwards

Question 3

A sky diver reaches terminal velocity when jumping out a plane. What does terminal velocity look like on a speed time graph?

Answer 3

Horizontal line at a constant speed

Question 4

What can you say about the forces acting on an object when the speed time graph is a horizontal straight line?

Answer 4

Forces are balanced
