State which word from the list correctly completes each statement, "Whenever there is a change in motion, a ____________ has acted."

State which word from the list correctly completes the statement, "A force can be measured using a ____________ balance."

State which word from the list correctly completes the statement, "The unit used to measure a force is called the ____________."

If the forces acting on an object are balanced, then it is not moving or travelling at a constant speed.

You apply a force when you squeeze a tube of toothpaste.

Inertia describes the tendency of an object to change its motion.

Draw a free-body diagram to accurately represent the effect forces have on a book resting on a table.

Draw a free-body diagram to accurately represent the effect forces have on an apple falling from a tree.

Draw a free-body diagram to accurately represent the effect forces have on a cyclist riding down a hill on a bicycle, increasing in speed.

Draw a free-body diagram to accurately represent the effect forces have on a cyclist moving at a constant speed in a forwards direction.

Which of these are examples of applying a force?

Which of the following are types of forces?

A magnetic force is a contact force.

A north pole of one magnet is attracted to the north pole of another magnet.

Identify the two different forces that act on a sky diver falling towards earth.

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 ________?

Explain the difference between contact and non-contact forces. Give an example of each.

The net force acting on an object is:

Balanced forces have a net force of:

In the image of the tug of war shown, the net force is:

The diagram provided shows all of the forces acting on an object. The forces can best be described as:

Two women push a broken-down car. They both push to the right with 150 N of force.

Finish the formula: Force = Mass x _________

What is friction?

Friction acts in the same direction as an object’s motion.

The greater the weight of the sliding object, the less force of friction it experiences.

Friction always acts "backwards" – in the direction opposite to an object's motion.

What is gravity?

Which force always pulls downward on objects?

A change to an objects motion is caused by...

When you walk across the ground and push on it with your feet...

Describe the motion of a person not wearing a seat belt if the car stops suddenly.

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.

Select ONE of Newton’s three laws of motion to describe ONE safety feature that car manufacturers include when developing new cars.

- Identify the link between Newton’s law of motion and the selected safety feature

-  Describe in detail how Newton’s law of motion is evident in the selected safety feature (i.e. describe the science of forces involved)

-  Provide an example
