Question

Statement 1: Walking on the surface of Earth is possible due to friction.
Statement 2: If there was no friction, the bodies would either slip or not move.

• A.
  Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
• B.
  Both statements 1 and 2 are true and statement 2 is not the correct explanation of statement 1.
• C.
  Statement 1 is true but statement 2 is false.
• D.
  Both statements 1 and 2 are false.

Answer 1

The correct option is A

Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
It is due to friction that we are able to walk on the surface of Earth. When we walk, we apply a backward force on the earth surface and friction pushes us forward. Without friction, we would either be slipping or not moving. Hence, both statements are correct and statement 2 is the correct explanation of statement 1.
