What is a free body diagram?

Back

A free body diagram is a graphical representation used to visualize the forces acting on an object. It shows the object as a dot and the forces as arrows pointing in the direction of the force.

How do you determine the net force acting on an object?

Back

The net force is determined by vectorially adding all the individual forces acting on the object. Forces in the same direction are added, while forces in opposite directions are subtracted.

Front

What does a net force of 0 N indicate about an object's motion?

Back

A net force of 0 N indicates that the object is either at rest or moving at a constant velocity, meaning there is no acceleration.

Front

What is the significance of the direction of forces in free body diagrams?

Back

The direction of forces is crucial as it determines the net force and the resulting motion of the object. Forces acting in opposite directions will affect the net force calculation.

Front

What does it mean if the net force is directed to the left?

Back

If the net force is directed to the left, it means that the overall effect of all forces acting on the object results in a movement or acceleration towards the left.

How can gravitational force be represented in a free body diagram?

Back

Gravitational force can be represented as an arrow pointing downward from the center of the object, with a length proportional to the weight of the object.

Front

What is the formula for calculating net force?

Back

The formula for calculating net force (F_net) is F_net = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.

What does a rightward gravitational force of 100 N imply in a free body diagram?

Back

A rightward gravitational force of 100 N implies that there is a force acting on the object in the right direction, which may be due to an external influence, as gravity typically acts downward.

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F_net = m * a).

Front

How do you represent forces acting in opposite directions in a free body diagram?

Back

Forces acting in opposite directions are represented by arrows pointing in opposite directions. The length of the arrows indicates the magnitude of the forces.
