section 1

Question 1

what are the two types of quantities and what makes them different

Answer 1

vector quantity - has both a direction and magnitude (size)
scalar quantity - only has a magnitude (size)

Question 2

list 6 vector quantities

Answer 2

force, velocity, displacement, weight, acceleration, momentum

Question 3

list 6 scalar quantities

Answer 3

speed, distance, mass, energy, temperature, time

Question 4

state the formula to work it out distance travelled (include units)

Answer 4

distance travelled (m) = (average) speed (m/s) x time (s)

Question 5

state the typical speed of walking in m/s and km/h

Answer 5

1.4 m/s, 5 km/h

Question 6

state the typical speed of running in m/s and km/h

Answer 6

3 m/s, 11km/h

Question 7

state the typical speed of cycling in m/s and km/h

Answer 7

5.5 m/s, 20 km/h

Question 8

Answer 8

13 m/s, 47 km/h

Question 9

state the typical speed of aeroplanes in m/s and km/h

Answer 9

250 m/s, 900km/h

Question 10

state the typical speed of car and a motorway in m/s and km/h

Answer 10

31 m/s, 112km/h

Question 11

state the typical speed of trains in m/s and km/h

Answer 11

up to 55 m/s, 200km/h

Question 12

state the typical speed range of wind speed in m/s

Answer 12

5 - 20m/s

Question 13

state the typical speed range of wind speed in m/s

Answer 13

5 - 20 m/s

Question 14

state the speed of sound in air in m/s

Answer 14

340 m/s

Question 15

state the typical speed of ferries in m/s and km/h

Answer 15

15 m/s, 54 km/s

Question 16

state the equation for acceleration, include units of measurements

Answer 16

a (m/s2) = v-u (m/s) / t (s)
acceleration = final velocity - initial velocity / time
