load.
Q2] Differentiate between contact forces and Force of Gravity

Answer 1

✨hey mate!✨
======================================>
(1) Porters place a round piece of cloth on their head when they carry heavy loads as the round piece of cloth increases the area on which the load is placed. We no that when surface is more than pressure is less. As a result, the pressure on their heads get reduced.

(2)
CONTACT FORCE :-
• Contact forces are those forces that act on bodies when they are in contact ‘Physically’.

• these types of forces are in direct contact.

• Eg) Boy pushing a block of wood.

NON - CONTACT FORCE / FORCE OF GRAVITY :-
• Non contact forces are those forces in which the force acts on the bodies even when they are not in contact.

• these types of forces are at a distance and not in direct contact.

• Eg) Gravitational and electrostatic forces.
