A mass m is placed on an inclined plane (m > 0) and slides down the plane with constant speed. If a similar block (same m) of mass 2m were placed on the same incline, it would:

  • For 2m, the gravitational force pressing downward on the plane is twofold.
  • However, the normal force is also doubled, and as a result, so is the friction force (the same factor).
  • This indicates that the two forces continue to cancel and produce a net force of zero.

Gravitational force

  • The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface.
  • The attracting force that the earth exerts on all other objects in the cosmos is known as gravitational force.
  • A ball being flung high and then falling back to the earth as a result of gravitational force is an example of gravitational force.
