Friction is a force which -
1. Acts in the same direction to that which you are moving in
2. Acts in the opposite direction to that which you are moving in
3. Acts downwards
4. Acts upwards
Friction is a force and it is measured in units called

Friction is force. How is friction caused?
1. One surface moving
2. Two surfaces being pushed together
3. Two surface being pulled apart
4. Two surfaces being rubbed together
The effect of friction is that it can
1. Speed you up
2. Slow you down
3. Push you onto the ground
4. Make you bigger
Which of the following are ways to increase friction? Tick all those which apply.
1. Use smooth surface to rub together
2. Use rough surfaces to rub together
3. Use small surfaces to rub together
4. Use large surfaces to rub together
5. Push the surface together hard
6. Push the surfaces together gently
Where is friction useful in a bicycle?
1. In the chain
2. For the brakes
3. On the seat
4. To ring the bell
Which of the following gives one way of reducing friction?
1. Oiling
2. Painting
3. Gripping the object
4. Pushing the object
Which of the following are examples of reducing friction?
1. Waxing Skis
2. Oiling the chain of a bike
3. Using the brakes on a car
4. Putting on rough soled boots to go hillwalking
5. Using sandpaper
6. The grip areas on tennis racquets or golf clubs
What is meant by the term streamlining?
1. Shaping an object to reduce air or water resistance
2. Improving an object so it can brake faster
3. Putting slick tyres on a car so it can go faster
4. When a car brakes on ice and slides
What is meant by air or water resistance?
1. It is the force of friction caused by air or water on an object
2. It is the push that air or water can give an object so it goes faster
3. It is the force of air or water squashing an object
Which of the following describe a streamlined shape?
1. Low to the ground
2. High off the ground
3. Boxy shape
4. Rough surface
5. Smooth surface
6. Rounded body shape
7. Lots of curves
When it is wet a car takes longer to stop. Why is this?
1. The water increases the friction between the tyres and the road so you can brake later
2. The water decreases the friction between the tyres and the road so it takes longer to stop
3. The water makes the car difficult to steer so it takes longer to stop.
4. The water increases the friction so you have more grip.
