1
Q
Weight
A
The gravitational force that earth exerts on any object near its surface
2
Q
Normal force
A
The perpendicular force exerted by a surface on an object in contact with it
3
Q
Friction:
A
The force which opposes the motion of an object friction acts parallel to the surface the object is in contact with. Friction occurs whenever two surfaces move across each other. Friction depends on the roughness of both surfaces.
4
Q
Static friction:
A
the friction between two solid objects that are not moving relative to each other.
5
Q
Kinetic friction:
A
The friction which occurs when two objects slide across each other or rub togeather
6
Q
