The static frictional between a 500 kilogram box of bricks and the floor is 500 Newton’s. The kinetic frictional force in only 220 Newton’s. How many Newton’s of force must a worker exert to get the moving?
Physical Science -
you need 500 N to overcome the static friction
as is frequently the case; once something starts, it is easier to keep it moving
