What is a force diagram?

Back

A visual representation that shows all the forces acting on an object, including their direction and magnitude.

Front

What does the length of an arrow in a force diagram represent?

Back

The strength of the force; longer arrows indicate stronger forces.

Front

What is the normal force?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object, acting parallel to the surfaces in contact.

Front

What happens to a skydiver when they open their parachute?

Back

The skydiver experiences an increase in air resistance, which slows them down.

Front

What is the net force acting on an object moving at a constant speed?

Back

The net force is zero, meaning all forces acting on the object are balanced.

Front

How do you determine the direction of a force in a force diagram?

Back

The direction of the arrow indicates the direction of the force applied to the object.

Front

What is the role of gravity in a force diagram?

Back

Gravity is a force that pulls objects toward the center of the Earth, acting downward on all objects.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects that are not moving, while kinetic friction acts on objects that are sliding past each other.

Front

How can you increase the normal force on an object?

Back

By increasing the weight of the object or adding additional forces acting downward.
