Question

A force is a push or pull on an object that could affect its motion. Which is an example of a non-contact force?

Answer 1

This question is incomplete.

Step-by-step explanation:

Force is classified either as contact or non-contact force.

A contact force is a force that requires physical contact/touch with the object. For example, the pushing of a car, the kicking of a ball and the pulling of a door.

Non-contact force is a force that does not require a physical touch/contact with the object. Examples of non-contact force is the force of gravity that pulls object towards itself on earth, force that repels two magnets (of like/similar pole facing each other) and the force that pulls a metallic object in a magnetic field.

Answer 2

`\boxed{\text{Electrostatic and magnetic forces}}`

Step-by-step explanation:

I can think of two non-contact forces:

• Electrostatic: the attractive or repulsive forces between two charged particles
• Magnetic: the attractive or repulsive forces between two magnetic poles.
