A force of friction is any force that opposes the motion of an object due to the contact of the object with other bodies. This time the force of friction is larger because it is proportional to the normal force exerted by the floor on the box which itself is equal to the weight of the box.
Force of friction is the force that help to stop anything
3)area of contact
4)density of liquid
6)i)pushing a car up a hill
ii)kicking a ball
8)non contact force
c) muscular, mechanical, friction
1- SI unit of force is Newton
2-pascal is a SI unit of pressure
3.dPlease do follow me for further support
i don't know the answer so sorry
The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.
