Motion of body on horizontal surface
Motion of a Body on a Horizontal Surface with Friction:
- Friction is the force that opposes motion between two surfaces in contact.
- When a body is placed on a horizontal surface and pushed, friction acts in the opposite direction to the push and opposes its motion.
- The frictional force is proportional to the normal force acting on the body, and it depends on the coefficient of friction between the two surfaces.
- If the frictional force is equal in magnitude to the force applied to the body, the body will not move.
- If the force applied to the body is greater than the frictional force, the body will accelerate in the direction of the applied force.
- The frictional force acting on a body moving with a constant velocity is equal in magnitude to the force applied, but opposite in direction.
- The frictional force acting on a body slowing down or coming to rest is greater in magnitude than the force applied, and opposite in direction.
- The frictional force can be calculated using the equation: frictional force = coefficient of friction * normal force.
