Understanding Friction and Its Effects

What is friction primarily caused by?

• The temperature of the environment

• Two surfaces rubbing against each other

• The weight of an object

• The color of an object

Why do smooth surfaces create less friction?

• They have more bumps and grooves

• They are colder

• They allow objects to glide more easily

• They are heavier

Which scenario would likely have the most friction?

• Sliding a box on a smooth wooden floor

• Walking on slippery ice

• Gliding down a smooth playground slide

• Running with sports shoes on a rough road

How does increasing the weight on a sled affect friction?

• It increases the friction

• It makes the sled lighter

• It decreases the friction

• It has no effect on friction

In which situation would you want to increase friction?

• When you want to stop rapidly and safely

• When you want to move quickly

• When you want to reduce wear and tear

• When you want to slide easily
