Free-Body Diagrams, Friction, Action and Reaction

Front

What is a Free-Body Diagram?

Back

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

Front

What does friction do in motion?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How do you calculate the net force on an object?

Back

Net force is the vector sum of all forces acting on an object.

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is kinetic friction?

Back

The force that opposes the motion of two surfaces sliding past each other.

Front

What is the formula for calculating frictional force?

Back

Frictional force = coefficient of friction × normal force.

Front

What happens when the applied force exceeds static friction?

Back

The object will start to move.

Front

What is the coefficient of friction?

Back

A numerical value that represents the frictional force between two surfaces.

Front

What is the role of normal force in free-body diagrams?

Back

Normal force acts perpendicular to the surface and supports the weight of the object.
