Applied Mechanics and Graphic Statics
If g1 and g2 are the gravitational accelerations on two mountains A and B respectively, the weight of a body when transported from A to B will be multiplied by
The force of friction always acts in a direction opposite to that in which a body is moving
For moderate speeds the force of friction remains constant but decreases slightly with the increase of speed
All of these
The magnitude of the kinetic friction bears a constant ratio to the normal reaction between two surfaces. The ratio being slightly less than that in the case of limiting friction
