  • IF the body is very light
  • If the surface has large friction
  • Depends on the surrounding atmosphere

  • If the car has fuel and no fault then yes

4)
Frictional force is not present if –
  • The body is rolling
  • If the body is sliding
  • If sliding and rolling

Mark the wrong one – Frictional force cause constant loss of energy if –
