What is a force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What are the two main types of forces?

Back

The two main types of forces are contact forces and non-contact forces.

Front

What is a contact force?

Back

A contact force is a force that requires physical contact between two objects, such as friction, tension, and normal force.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts at a distance without physical contact, such as gravitational force, magnetic force, and electrostatic force.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, which pulls them toward each other.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

What is friction?

Back

Friction is a contact force that opposes the relative motion of two surfaces in contact.

Front

What is tension?

Back

Tension is a pulling force transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends.

Front

What is normal force?

Back

Normal force is the support force exerted upon an object that is in contact with a stable surface.

Front

What is an example of a pull force?

Back

An example of a pull force is when a dog pulls on a leash.
