A block of mass m is sitting motionless on a plane with an incline of θ, a coefficient of
static friction of μs and a coefficient of kinetic friction μk. Which of the following will
occur once the plane is elevated on one side, increasing θ?
Answers
When there is an increase in the angle of inclination, the normal force decreases. As a result, the static force of friction as well as the kinetic force of friction both decrease.
. Static friction is a force that is responsible for keeping the object in a state of rest.
. Kinetic friction is the force that resists the relative movement of the surfaces once they're in motion.
. When the angle of inclination increases, the normal force decreases. As a result, static frictional force decreases.
.The kinetic force of friction decreases with an increase in the angle of inclination, as the normal force acting on the block of mass 'm' decreases. As there is less force pressing the surfaces of the two objects together, there is less kinetic friction generated between the two surfaces.
