Types of Forces Flashcards

Front

What are contact forces?

Back

Forces that occur when two objects are physically touching each other, such as friction and applied force.

Front

What are non-contact forces?

Back

Forces that act on an object without physical contact, such as gravity and magnetism.

Front

How does gravity act on objects?

Back

Gravity is a non-contact force that pulls objects toward each other, like the Earth pulling objects toward its center.

Front

What is friction?

Back

Friction is a contact force that opposes the motion of objects sliding or rolling over each other.

Front

What is magnetism?

Back

Magnetism is a non-contact force that can attract or repel certain materials, like iron, due to magnetic fields.

Front

What is a normal force?

Back

Normal force is a contact force exerted by a surface perpendicular to an object resting on it, supporting the object's weight.

Front

What is an applied force?

Back

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