What are forces X and Y?
X is air resistance, Y is gravity
X is air resistance, Y is friction
X is weight, Y is air resistance
X is friction, Y is air resistance
Balanced forces...
make objects speed up
make objects slow down
do not change the speed of moving objects
only affect stationary objects
A boat has a forward force on it of 500 N and water resistance is 400 N. Which statement is true?
the forces are balanced and the boat will go faster
the forces are balanced and the boat will continue to move at the same speed
the forces are unbalanced and the boat will go faster
the forces are unbalanced and the boat will continue to move at the same speed
All vehicles have a top speed. This is when...
the air resistance is the same as the force from the engine
the drag and friction forces balance the maximum force from the engine
the force from the engine balances friction from the wheels
the drag forces balance the friction forces
Which of these is not a way in which energy is stored?
chemical
kinetic
friction
thermal
Which of these is a way in which energy can be transferred?
movement
petrol
light
potential
In which ways is energy most often transferred as wasted energy?
heating and light
heating and sound
sound and light
sound and kinetic
Which of these machines is more efficient and why?
Y because it does not waste as much energy as X
Y because it wastes more energy than X
X because it transfers the most energy
X because it wastes more energy than Y
The speed of a car is a measure of how...
far it is travelling
fast it is travelling
long it is travelling
high it is travelling
A bus travelled a distance of 20 km in 2 hours. Its speed was:
0.1 km/h
40 km/h
20 km/h
10 km/h
The average speed of something is...
its fastest speed
the total distance it travels divided by the total time taken
its slowest speed
its speed limit

V to W
W to X
X to Y
Y to Z
Which are the correct labels for the lever shown below?
X = load, Y = pivot, Z = effort
X = effort, Y = pivot, Z = load
X = pivot, Y = effort, Z = load
X = load, Y = effort, Z = pivot
Which lever will make it easiest to move the rock?
A
B
C
D
You are opening a can of paint with a screwdriver. You apply a force of 10 N,
0.2 m from the pivot. What is the moment of the force?
2 Nm
20 Nm
200 Nm
2000 Nm
The seesaw is balanced. What is the distance between the boy and the pivot?
1 m

4 m
Which of these is not a simple machine?
lever
bicycle
ramp
pulley
Which of these statements is true?
A ramp can be a force multiplier or a distance multiplier
A machine can make it possible to move a load using a smaller force
A machine makes it possible to move an object with less work
Shallow ramps make it harder to lift loads than steep ones
A pulley system allows you to lift a 100 N weight using only a force of 50 N. How is energy conserved in the pulley systems?
The rope will be pulled for double the distance that the weight moves
The rope will be pulled by the same distance that the weight moves
The rope will have to be pulled only half the distance the weight moves
There is not much friction in the pulleys

15 N
15 J
30 J
60 J
