Net force and energy test review

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, most notably the force that pulls objects toward the Earth.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without physical contact, such as gravity or magnetism.

Front

What is magnetism?

Back

Magnetism is a non-contact force that can attract or repel objects, depending on their magnetic properties.

Front

What is friction?

Back

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

Front

How do you calculate net force?

Back

Net force is calculated by adding all the forces acting on an object, taking into account their direction.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, causing the object to accelerate in the direction of the greater force.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is an example of an applied force?

Back

An applied force is a force that is applied to an object by a person or another object, such as pushing a box.
