Question
Jack is going skiing. How much friction does he need?
- More
- Less
- Does not matter
- None of the above
Hint:
Skiing is the use of skis to glide on snow. and for smooth sliding we need less friction
The correct answer is: Less
- Friction is a type of contact force. It exists between the surfaces which are in contact.
- Friction is generally rubbing of surface
- Skiing is the use of skis to glide on snow
- So for gliding we need less friction so that we can slide easily on snow

How does friction affect speed?
Friction is the force opposing one solid object's movement over another. Four categories of friction exist fluid friction, rolling friction, sliding friction, and static friction.
¶The frictional force keeps our feet planted on the ground when we walk on or on the floor. As a result, we frequently slip on icy or slippery surfaces because there is less friction.
¶According to scientists, friction is caused by the interactions of tiny bumps on surfaces as they rub against each other. The bumps on each surface bend and exert force on each other, making it difficult for the surfaces to slip over each other.
