Chapter 5.1: Characteristics of Motion

Question 1

Define distance

Answer 1

Distance is how far an object travels

Question 2

Define displacement

Answer 2

Displacement is the overall change in position of an object and its direction

Question 3

List the units of distance and/or displacement

Answer 3

Metres (m), kilometres (km), and centimetres (cm)

Question 4

Compare scalar and vector quantities

Answer 4

Scalar quantities only have magnitude and on the other hand, vector quantities have both magnitude and direction

Question 5

What are displacement-time graphs also known as?

Answer 5

Position-time graphs

Question 6

Define speed

Answer 6

Speed is how fast an object travels

Question 7

Define velocity

Answer 7

Velocity is the speed in a particular direction

Question 8

Identify the units used to measure speed and/or velocity

Answer 8

Metres per second (ms^-1) and kilometres per hour (kph)

Question 9

Define acceleration

Answer 9

Acceleration is the rate of change of speed

Question 10

Define deceleration

Answer 10

Deceleration is a negative rate of change of speed

Question 11

Identify the units used to measure acceleration

Answer 11

Metres per second per second (ms^-2)
