A minibus is travelling along a flat bitumen road. Identify two sources of friction that are acting on the vehicle.
A car is travelling from Cairns to Melbourne. The weather conditions change from dry, to wet to icy over the course of the drive. Which type of weather condition will the car have most friction on the road?
A mountain bike is designed to be considerably heavier than a road bike. How does the increased mass of the mountain bike assist the rider to travel up a gravel hill in comparison to a road bike travelling up a gravel hill? Make reference to friction and mass.
A man pushes a trolley. Force A pushes the trolley forwards, while force B pushes against the trolley to oppose the motion.
Force A is ________ and force B is ________?
friction; applied
applied; air resistance
tension; gravity

Explain the difference between contact and non-contact forces. Give an example of each.
The net force acting on an object is:
The weakest force
The strongest force
The downward force
The overall force acting on an object
Balanced forces have a net force of:
0 N
50 N
100 N
It depends on the scenario
In the image of the tug of war shown, the net force is:
50 N to the right
200 N to the left
250 N to the right
450 N to the right
The diagram provided shows all of the forces acting on an object. The forces can best be described as:
balanced, with a net force of 0 N
unbalanced, with a net force of 5 N to the right
unbalanced, with a net force of 5 N to the left
unbalanced, with a net force of 20 N to the right
Two women push a broken-down car. They both push to the right with 150 N of force.

What is friction?
A force that speeds up objects
A force that works in the opposite direction to an object's motion
A force that slows down an object by pulling it downwards
A force that causes stretched objects to return back to their original shape
Friction acts in the same direction as an object’s motion.
True
False
The greater the weight of the sliding object, the less force of friction it experiences.
True
False
Friction always acts "backwards" – in the direction opposite to an object's motion.
False – friction can also act "forwards", causing objects to speed up.
True – friction is a non-contact force that pulls moving objects back towards where they started moving.
True – friction is a contact force that slows things down.
False – friction is not a force, it just slows things down.
What is gravity?
An inward pulling force that occurs when a solid object is stretched.
A force of attraction between materials that contain iron, cobalt or nickel.
A force of attraction between all objects that have mass.
A push, pull or twist on an object.
Which force always pulls downward on objects?
Support force
Friction force
Gravity
Air resistance
A change to an objects motion is caused by...
Balanced forces
Unbalanced forces
Acceleration
Velocity
When you walk across the ground and push on it with your feet...
There is no effect on the ground.
The ground pushes back less strongly than your feet.
The ground pushes back more strongly than your feet.
The ground pushes back on your feet with equal force.
Describe the motion of a person not wearing a seat belt if the car stops suddenly.
The person and car will stop together.
The person will stop faster than the car because they are lighter.
The car will stop and the person will keep moving forward because of inertia.
The car will stop and the person will speed up.
Describe the role of the following safety features in protecting passengers of a car in an accident: seat belts and airbags.
Explain why cars are designed with crumple zones.
