Inlined Planes

Question 1

State the relationship between the normal and weight forces of an object placed on a flat surface.

Answer 1

They are equal

Question 2

For an object sliding down a slope, what does the perpendicular and parallel components of the weight force represent?

Answer 2

The perpendicular component represents the normal force and the vertical force represents the net force.

Question 3

Describe the conditions for an object to remain at rest on an inclined plane with friction. What must the frictional force be equal to?

Answer 3

The frictional force must be equal to the applied force to the object. If there is no applied force, then the frictional force must be equal to 0.
