What ‘B’ describes the forces acting on an object when it is at rest?
(a)
If an object moves, which is greater? The push or frictional force?
Push force
Frictional force
Which is harder?
A: Start an object moving against a frictional force.
B: Keep an object moving against a frictional force.
A
B
True or False: The smoother the surface, the greater the friction.
True
False
Which unit is friction measured in?
(a)
What causes friction?
What is friction?
The force that stops something from moving
The force that pushes an object
The force that can slow down or stop a moving object
The force that pull an object
What will happen to an object if the frictional force is less than the push force?
(a)
Tick the ways that you can reduce friction.
Lubricate the joint
Make joining surfaces smoother
Reduce the pressure on the joining surfaces
Tilt the joining surfaces on an angle
What happens when someone pushes an object?
Which surface will provide the greatest friction?
Ice
Wood
Coarse sandpaper
Select the correct possible methods of lubrication.
Oil
Rubber
Grease

Silicon
What is the name of the force required to keep an object moving?
(a)
Name the measuring device that can be
used to measure friction.
Newton meter

Force meter
Which is harder?
Start an object moving against a frictional force.
Keep an object moving against a frictional force.
What is the name of the friction before the object starts moving?
(a)
Where would friction be useful?
Bike brakes
Tyres of the road
Sports trainers
What effect does lubricant have on the amount of friction?
Friction is increased
Friction is removed
Friction is decreased
Friction is added
How can it be described when an object does not slip down a slope?
The frictional force is less than the force acting along the slope due to gravity.
The friction force is greater than or equal to the force acting along the slope due to gravity.
The friction force must be greater than the force acting along the slope due to gravity.
True or False: Friction is a force that
opposes motion.
True
False
How can you measure friction?
You can pull an object with a
Force meter and measure how
much force is required to move it.
You can't
You can pull an object with a
Newton meter and measure how
much force is required to move it.
You can push an object with a
Pushometer and measure how
much force is required to move it.
What are Newtons a measure of?
