21
Q

Displacement (definition)

A

The distance covered in a straight line

22
Q

Velocity (definition)

A

Speed in a particular direction

23
Q

acceleration (definition)

A

a measure of how fast velocity is changing

24
Q

momentum (definition)

A

a combination of mass and velocity

25
Q

Vector or Scalar? - Upthrust

A

Vector

26
Q

Describe the differences between mass and weight

A

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

27
Q

Explain why displacement is a vector quantitiy

A

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

28
Q

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

A

0 metres

29
Q

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

A

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

30
Q

Speed (defintition)

A

How fast an object moves in a certain amount of time
