Real Friction practice questions
Which produces more friction when an object slides across it: a rough surface or a smooth surface?
A smooth surface
A rough surface ✓
Rough surfaces have more bumps and grooves that catch against each other, producing more friction than smooth surfaces.
Which of these methods of moving a heavy box across the floor involves the MOST friction?
Sliding a box directly on the floor ✓
Moving a box on a trolley with wheels
Rolling a box on round logs
Pushing a box on roller skates
Sliding a box directly on the floor creates more friction than using wheels, logs or skates, because more surface area rubs against the ground without anything to reduce the contact.
Why do many bathrooms have rubber non-slip mats on the floor?
To keep the floor cooler
To reduce the amount of water on the floor
To make the bathroom look decorated
To increase friction and prevent people from slipping ✓
Non-slip mats have a rough, bumpy surface that increases friction, helping to prevent people from slipping on wet bathroom floors.
In which direction does friction generally act on a moving object?
In the opposite direction to the movement ✓
In the same direction as the movement
Always straight downward
Always straight upward
Friction acts in the opposite direction to an object's movement, which is why it slows the object down or resists its motion.
