Question

Q3=Define these of the following:
[a] Muscular force
[6] Electrostatic force
[C] Gravitational force
[d] Pressure
[E] Atmospheric pressure​

Answer 1

Answer:

Muscular Force: The force exerted by the muscles of our body is known

as Muscular Force.

e) Friction : The force that opposes the motion of an object is called

Friction

f) Mechanical Force: The Force produced by a Machine is called a

Mechanical Force.

g) Magnetic Force : The force exerted by a Magnet is called Magnetic

Force

h) Electrostatic Force: The force exerted by a charged body on another

charged or uncharged body is known as electrostatic forces.

i) Gravitational Force: Gravitation force is the force with which any two

masses or objects pull each other.

j) Gravity: Gravity is the force with which the earth attracts towards

itself.

k) Pressure: Pressure is defined as the force acting on a unit area of a

surface.

l) Atmospheric Pressure: The pressure exerted by the weight of the air on

an object is called atmospheric pressure.

Answer 2

Answer:

☞Muscular force?⤵

ans:Muscular force is the force applied using parts of the body like arms or legs. It is force that results due to the action of muscles, and is a contact force, since there is a contact between the surfaces. Muscular force is needed whenever movement of the body occurs.

☞Electrostatic Force? ⤵

ans:The electrostatic force is an attractive and repulsive force between particles are caused due to their electric charges. The electric force between stationary charged body is conventionally known as the electrostatic force. It is also referred to as Columb's force.

☞Gravitational force? ⤵

ans: Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

☞pressure? ⤵

ans: Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. ... In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

☞Atmospheric pressure? ⤵

ans: the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).
