Answer 1

described by only magnitude

Question 2

vector

Answer 2

described by magnitude AND direction

Question 3

distance

Answer 3

how much ground was covered (scalar)

Question 4

displacement

Answer 4

how far the object is from the start (vector)

Question 5

what does the slope represent on a p-t graph?

Answer 5

velocity

Question 6

what does the slope represent on a v-t graph?

Answer 6

acceleration

Question 7

what is the difference between speed and velocity?

Answer 7

Speed is a scalar quantity (magnitude only) but velocity is a vector quantity (includes direction) velocity can be negative, speed can’t

what does it mean if the line is going downwards on a p-t graph?

Answer 9

it’s moving in a negative direction

Question 10

if the slope is decreasing on a p-t graph, so is…

Answer 10

the velocity

Question 11

what is acceleration?

Answer 11

the change in velocity per unit of time
