Unit 6 concept 2

Question 3

Explain the difference, in relation to speed, between positive and negative acceleration, sketch and label each. Be sure to label your axes.

Answer 3

Positive acceleration:
D vs t graph= line steady curving up
V vs t graph= straight line from bottom left to top right

Negative acceleration:
D vs t graph= line going up and slowly flattening out
V vs t graph= strait line going from top left to bottom right.
