Front

What type of force is electrical force?

Back

Electrical force is a force at a distance, meaning it can act over a space without direct contact.

Front

What type of force is gravity?

Back

Gravity is also a force at a distance, acting between masses without direct contact.

Front

What type of force is air resistance?

Back

Air resistance is a contact force that opposes the motion of an object through the air.

Front

Back

Contact force is a force that occurs when two objects are physically touching each other.

Front

Define force at a distance.

Back

Force at a distance is a force that can act on an object without physical contact, such as gravitational or electrical forces.

Front

What is an example of a contact force?

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

Front

What is an example of a force at a distance?

Back

Magnetic force is an example of a force at a distance, acting between magnets without direct contact.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object, slowing it down or preventing it from moving.
