... 7) What is the meaning of the expression ΣF = 0? Answer: This is the mathematical expression for the equilibrium rule, which states that the vector sum of the forces acting on an object is equal to zero if that object is in a state of rest, or a state of unchanging velocity. "Vector sum" means that ...

... When two surfaces are pressed together, the high points on each side come into contact and form molecular bonds. The amount of contact depends on the normal force n. When the two surfaces are sliding against each other, the bonds don’t form fully, but they do tend to slow the motion. © 2013 Pe ...

... Walking on the Moon On Earth, acceleration due to gravity is about 9.8 m/s2. Acceleration due to gravity is determined by the magnitude of the gravitational force on the surface of Earth, which is in turn determined by Earth’s mass and radius. As you may know, objects weigh less on the Moon than on ...
