Understanding Free Body Diagrams

What is the primary force acting on an object in midair?

• Tension

• Weight

• Friction

• Reaction force

How does a plain surface affect the forces acting on an object?

• It adds a reaction force perpendicular to the surface

• It adds a vertical force

• It adds a horizontal force

• It adds a tension force

What happens to friction on a rough plane?

• It acts perpendicular to the surface

• It acts in the direction of motion

• It does not act at all

• It acts in the opposite direction of motion

In what way can force be applied on an inclined plane?

• Only perpendicular to the plane

• Only vertically

• Only horizontally

• Along the plane or at an angle

How are forces broken down on inclined planes?

• Into horizontal and vertical components

• Into parallel and perpendicular components

• Into tension and friction components

• They are not broken down
