2.1 Motion

Question 1

Distance & Displacement

Answer 1

Both measure how far something travels - displacement is direction in which it travelled

Question 2

Velocity

Answer 2

Both speed and direction

Question 3

Scale Quantities

Answer 3

Speed, Distance, Mass, Time - measured in time

Question 4

Vector Quantities

Answer 4

Velocity, Force, Acceleration - measured in time and direction

Question 5

Vectors

Answer 5

Can be positive and negative directions - Speed = distance divided by time

Question 6

Acceleration

Answer 6

How fast your speeding up, change in velocity in a certain amount of time - acceleration = change in velocity divided by time - deceleration is just negative acceleration

Question 7

Distance Time Graphs

Answer 7

Show motion of an object, how far something has travelled, gradient is rate of change - steep graph = rate of change of distance is bigger, curves show acceleration

Question 8

Straight Line of a Distance Time Graph

Answer 8

Change vertically divided by change horizontally

Question 9

Velocity Time Graphs

Answer 9

Finds acceleration, flat section = stable velocity and curve means changing acceleration, area under section of graph is equal to distance travelled in that time interval

Question 10

Density =

Answer 10

Mass divided by volume
