Motion of body on inclined surface

 Motion of a Body on an Inclined Surface with Friction:

  • An inclined surface is a surface that makes an angle with the horizontal plane.
  • When a body is placed on an inclined surface and pushed, friction acts in the opposite direction to the push and opposes its motion
  • In addition to friction, the force of gravity acts on the body and produces a component along the surface of the incline.
  • If the component of the gravitational force along the incline is greater than the frictional force, the body will accelerate down the incline.
  • If the component of the gravitational force along the incline is equal to the frictional force, the body will move at a constant velocity.
  • If the component of the gravitational force along the incline is less than the frictional force, the body will not move.
  • The frictional force can be calculated using the equation: frictional force = coefficient of friction * normal force.
  • The component of the gravitational force along the incline can be calculated using the equation: component = gravitational force * sin(angle of incline).
  • The normal force can be calculated using the equation: normal force = gravitational force * cos(angle of incline).
