Forces on Inclined Planes

Front

What is the normal force?

Back

The normal force is the force exerted by a surface that supports the weight of an object resting on it, acting perpendicular to the surface.

Front

What is the formula for calculating the normal force on an inclined plane?

Back

F_N = mg cos(ϴ), where m is mass, g is acceleration due to gravity, and ϴ is the angle of the incline.

Front

What is the direction of the normal force on an inclined plane?

Back

The normal force is always perpendicular to the surface of the incline.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

How do you calculate net force on an inclined plane?

Back

Net force can be calculated by subtracting the force of friction from the component of gravitational force acting down the incline.

Front

What is the formula for calculating acceleration on an inclined plane?

Back

a = (F_net) / m, where F_net is the net force and m is the mass of the object.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the coefficient of friction?

Back

The coefficient of friction is a dimensionless scalar value that represents the frictional force between two bodies in contact.

Front

What is the role of gravity on an inclined plane?

Back

Gravity causes an object to accelerate down the incline, and its effect can be resolved into components parallel and perpendicular to the surface.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from starting to move.
