Question 21

Displacement (definition)

Answer 21

The distance covered in a straight line

Question 22

Velocity (definition)

Answer 22

Speed in a particular direction

Question 23

acceleration (definition)

Answer 23

a measure of how fast velocity is changing

Question 24

momentum (definition)

Answer 24

a combination of mass and velocity

Question 25

Vector or Scalar? - Upthrust

Answer 25

Vector

Question 26

Describe the differences between mass and weight

Answer 26

Weight is a vector quantity meaning it has both direction and magnitude whereas mass measures the amount of matter in something, meaning it has only magnitude and therefore it is scalar quantity

Question 27

Explain why displacement is a vector quantitiy

Answer 27

Displacement is a vector quantity because it has both magnitude (in metres) and a direction

Question 28

Runners in a 400m race complete one circuit of an athletics track. What is their displacement at the end of the race?

Answer 28

0 metres

Question 29

Cyclists are riding around a roundabout. Explain why the cyclists' velocity will change even if they maintain the same speed

Answer 29

The bikes are constantly changing direction meaning the velocity changes too. Velocity is a vector quantity therefore it relies on magnitude and direction

Question 30

Speed (defintition)

Answer 30

How fast an object moves in a certain amount of time

Question 31

Vector or Scalar? - Volume

Answer 31

Scalar

Question 32

Vector or Scalar? - Displacement

Answer 32

Vector

Question 33

Vector or Scalar? - Weight

Answer 33

Scalar

Question 34

Vector or Scalar? - Moment

Answer 34
