friction and inclined planes, review

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to the horizontal, used to help raise or lower objects.

Front

What is the formula for calculating the force of friction?

Back

Frictional Force (F_f) = Coefficient of Friction (μ) × Normal Force (N).

Front

What is the coefficient of kinetic friction?

Back

The coefficient of kinetic friction (μ_k) is a dimensionless constant that represents the ratio of the force of kinetic friction between two bodies to the normal force pressing them together.

Front

How does the angle of an inclined plane affect the normal force?

Back

As the angle of an inclined plane increases, the normal force decreases because it is equal to the weight of the object multiplied by the cosine of the angle.

Front

What is the relationship between weight and normal force on an inclined plane?

Back

On an inclined plane, the normal force is less than the weight of the object due to the angle of inclination.

Front

What is the net force acting on an object on a frictionless incline?

Back

The net force is equal to the component of the weight acting down the incline.

Front

How do you calculate the component of weight parallel to an incline?

Back

Weight parallel (F_parallel) = Weight (W) × sin(angle).

Front

How do you calculate the component of weight perpendicular to an incline?

Back

Weight perpendicular (F_perpendicular) = Weight (W) × cos(angle).

Front

What happens to the acceleration of an object on an incline as the angle increases?

Back

As the angle of the incline increases, the acceleration of the object down the incline increases.
