FBD (FreeBodyDiagrams)

What is the primary purpose of a free-body diagram in physics?

• To visually represent the forces acting on an object

• To calculate the mass of an object

• To determine the speed of an object

• To measure the temperature of an object

Which symbol is commonly used to represent gravitational force in a free-body diagram?

• Fg

• Fk

• Fn

• Fa

What does the size of an arrow in a free-body diagram indicate?

• The magnitude of the force

• The type of force

• The direction of the force

• The object’s mass

How is net force calculated in one dimension using a free-body diagram?

• By subtracting forces in the negative direction from those in the positive direction

• By adding all forces together without considering direction

• By multiplying the forces acting on the object

• By dividing the forces by the object’s mass

In the example of a skydiver, what does a positive net force value indicate?

• The net force is directed upwards

• The net force is directed downwards

• The skydiver is accelerating downwards

• The parachute is not exerting any force
