Question

Classify the following forces into contact and non-contact forces. Gravitational force, frictional force, spring

force, magnetic force.​

Answer 1

Answer:

Gravitational force =contact force

Frictional force =contect force

Spring force =non-contact

Magnetic force =contact

Explanation:

please mark me as brainlist please

Answer 2

Answer:

They are such forces which are exerted on objects by direct contact. The forces which acts on bodies when they are in actual contact are called the contact forces.

The following forces come under Contact Forces.

Frictional forces

Normal reaction force

Tension force as applied through strings

Force exerted by a spring

Force exerted during collision

Force exerted by a spring

Force exerted during collision

Force applied as a pull or push

Non Contact Force:

The forces which act on bodies without being physically touched, are called the non-contact forces.

The following forces come under non-contact forces :

Gravitational Force

Electrostatic Force

Magnetic Force

Hence, the odd man out is magnetic force.
