Question

A toy with wheels released with the same initial speed will travel farthest on a ______.

  1. Muddy surface
  2. Mirror surface
  3. Cemented surface
  4. Brick surface

hintHint:

  • Lesser the frictional force, farthest the toy will travel

The correct answer is: Mirror surface


    • Lesser the frictional force, farthest the toy will travel
    • A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction.
    • Here mirror  surface has the least frictional force and least inertia hence toy will travel farthest  on a marble floor.

    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.
