Forces & Free Body Diagrams

Front

What is tension?

Back

Tension is the force exerted by ropes, strings, or chains when they are pulled tight.

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

What are paired forces?

Back

Paired forces are forces that act in opposite directions and are equal in size.

Front

How do you determine the direction of net force?

Back

The direction of net force is determined by the direction of the greater force acting on the object.

Front

What is normal force?

Back

Normal force is the force that acts perpendicular to a surface, supporting the weight of an object resting on it.

Front

What is the formula for calculating net force?

Back

Net force (F_net) = Sum of all forces acting on an object.

Front

What is static friction?

Back

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

Front

What is the difference between static and kinetic friction?

Back

Static friction acts on objects at rest, while kinetic friction acts on moving objects.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).
