Question

Smrita is climbing a mountain. How much friction does she need?

  1. More
  2. Less
  3. Does not matter
  4. None of the above

hintHint:

friction, is a force that resists the sliding or rolling of one solid object over another

The correct answer is: More


    • Friction is a type of contact force. It exists between the surfaces which are in contact
    • friction is a , force that resists the sliding or rolling of one solid object over another
    • On climbing   a mountain we need  our hands to stay on the mountain  or hands should be in contact with mountain so that our hands should not slip from the mountain
    • So for more  strong contact we need more friction

    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.
