In the previous chapter we found that the upper arm bone (humerus) exerts 480 lbs of force on the pinkie … WebThe force acting along the two surfaces in contact which opposes the motion or the tendency of motion of one body over the other is known as the force of friction or frictional force. It acts on both the surfaces in contact. Reason behind friction Force of friction arises due to the force of adhesion at the point of contact.

WebFrictional force = µ static wood-wood * N. where N = W and W = m * g = 50 kg * 9.8 m/s 2 = 490 N and µ static wood-wood = 0.20 (from the table above) Then, frictional force = 0.20 * 490 N = 98 N. The magnitude of the minimal force F to overcome static friction and set the bookshelf in motion is 98 N. Kinetic friction. WebFRICTIONAL FORCE. Frictional Force is a force that stops things from moving easily. It is friction that enables a nail to stay in a hole and hold two piece of wood together. It is friction that makes it possible for fire to occur by striking the two surfaces of two stones. how many perished on the titanic
