What is a Free-Body Diagram?

Back

A graphical representation used to visualize the forces acting on an object.

Front

What does the normal force do?

Back

It acts perpendicular to the surface and supports the weight of an object resting on it.

Front

What is weight force?

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

Define frictional force.

Back

The force that opposes the motion of an object when it is in contact with another surface.

Front

What is net force?

Back

The total force acting on an object, calculated by vector addition of all individual forces.

Front

What is static friction?

Back

The frictional force that prevents two surfaces from sliding past each other when at rest.

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on objects in motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is applied force?

Back

The force that is applied to an object by a person or another object.

Front

What is buoyant force?

Back

The upward force exerted by a fluid that opposes the weight of an object immersed in it.
