Question

Difference between w contact and noncontact forces

Answer 1

Answer:

Explanation:

1. CONTACT FORCES;

• Contact forces are those forces that act on bodies when they are in contact ‘Physically’.

• Boy pushing a block of wood.

• this  force obey Newton’s Law

• Frictional force, air resistence force, muscular force, etc.
• There is no field linked with the contact force

1. NON CONTACT FORCES;

• Non contact forces are those forces in which the force acts on the bodies even when they are not in contact.

• Gravitational and electrostatic forces

• this  force also obeys Newton’s Laws.

• There is always field linked with non-contact force.
