Free Body Diagrams

What is the primary purpose of a Free Body Diagram in physics?

• To illustrate the motion of an object over time.

• To isolate and analyze all forces acting on a single object.

• To calculate the total energy of a system.

• To determine the velocity and acceleration of an object.

Which of the following is classified as a distant force?

• Frictional force

• Normal force

• Magnetic force

• Applied force

What is the characteristic direction of a normal force?

• It acts parallel to the surface.

• It acts perpendicular to the surface.

• It acts in the same direction as the applied force.

• It acts only when an object is moving.

Under what condition does a tensional force typically arise?

• When an object is resting on a flat surface.

• When an object is being pushed horizontally.

• When an object is suspended by a rope or cable.

• When an object is experiencing air resistance.

What forces are acting on a blacksmith sign hanging motionless from a beam?

• Force of gravity and one force of tension.

• Force of gravity and two forces of tension.

• Force of gravity only.

• Two forces of tension only.
