U9 - Incline Forces: Trig, FBD Analysis, Prep Problems

Front

What is the normal force in a Free Body Diagram (FBD)?

Back

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

What is the weight of a bicyclist (including the bike) if it is given as 800 N?

Back

The weight of the bicyclist (including the bike) is 800 N.

Front

How do you determine the downhill weight of an object on an incline?

Back

The downhill weight can be calculated using the formula: W_downhill = W * sin(θ), where W is the weight and θ is the angle of the incline.

Front

What is the normal weight of a bicyclist (including the bike) on an incline if the weight is 800 N?

Back

The normal weight can be calculated using the formula: W_normal = W * cos(θ), where W is the weight and θ is the angle of the incline.

Front

What is net force in the context of an FBD?

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration according to Newton's second law.

Front

Define Free Body Diagram (FBD).

Back

A Free Body Diagram is a graphical representation used to visualize the forces acting on an object, isolating it from its surroundings.

Front

What role does gravity play in incline problems?

Back

Gravity acts downward on an object, and its components must be resolved into parallel and perpendicular forces relative to the incline.

Front

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

Back

The component of weight acting parallel to the incline is calculated using: W_parallel = W * sin(θ), where W is the weight and θ is the angle of the incline.

Front

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

Back

The component of weight acting perpendicular to the incline is calculated using: W_perpendicular = W * cos(θ), where W is the weight and θ is the angle of the incline.

Front

What is the significance of the angle of incline in force analysis?

Back

The angle of incline affects the distribution of forces acting on an object, influencing both normal and parallel force components.
