Physics of Inclined Planes Quiz

What determines the manner in which an object moves on an inclined plane?

• The color of the object

• The forces acting on the object

• The shape of the object

• The temperature of the environment

Which force always acts downward on an inclined plane?

• Gravitational force

• Normal force

• Tension force

• Frictional force

How does the force of friction act on an object sliding down an inclined plane?

• It acts in the direction of motion

• It acts perpendicular to the plane

• It acts downward

• It acts upward and parallel to the plane

What is the purpose of resolving the force of gravity into components on an inclined plane?

• To simplify calculations

• To change the direction of gravity

• To eliminate friction

• To increase the force

Which trigonometric function is used to find the component of gravity parallel to the inclined plane?

• Sine

• Cosine

• Cotangent

• Tangent

In a friction-free inclined plane scenario, what is the net force equal to?

• The tension force

• The perpendicular component of gravity

• The normal force

• The parallel component of gravity

What happens to the normal force when the plane is tilted?

• It remains vertical

• It increases

• It becomes zero

• It tilts with the plane

How is the net force calculated when friction is involved on an inclined plane?

• By subtracting friction from the parallel component

• By adding friction to the parallel component

• By dividing friction by the normal force

• By multiplying friction with the normal force

What is the effect of the 'tilted page trick' on the analysis of forces?

• It changes the angle of inclination

• It eliminates the need for calculations

• It makes forces appear vertical and horizontal

• It complicates the problem
