Module 2

Question 1

What is a position time graph

Answer 1

a graph that gives the objects position at a certain time

Question 2

what does a slope line represent and what does a straight horziontal line

Answer 2

slope - velocity

line - sitting still

Question 3

What is a velocity time graph

Answer 3

shows the motion of an object by showing changes in velocity over time

Question 4

What are three types of lines and what do they represent

Answer 4

constant velocity - straight flat horizontal line
acceleration - vertical diagonal line
going opposite direction - when below reference point

Question 5

Explain the what the area under a speed time graph repesents

Answer 5

the distance the object has traveled from start to that point (DISPLACEMENT OF OBJECT)

Question 6

How do you calculate the area of the complec line shapes

Answer 6

divide the shape into a series of traingles and rectangles

Question 7

On a speed time graph what does a horsiontal and sloping line represent

Answer 7

horizontal - constant speed

sloping - acceleration
