Force :-

It is a push or pull on an object that produces acceleration in the body on which it acts.

• A force can do 3 things on a body
• It can change the speed of a body.
• It can change the direction of motion of a body.
• It can change the shape of the body.

• Force = Mass × Acceleration

The S.I. unit of force is Newton.

Pressure :-

Pressure is defined as the force per unit area.

• Pressure depends on two factors:
• Force applied
• Area of surface over which force acts.

• Pressure = Thrust/Area

• Pressure is indirectly proportional to the surface area of the object, so, pressure increases with a decrease in surface area and decreases with an increase in surface area.

SI unit of pressure is Pascal also Newton/Meter².

Magnetic Force :-

Magnetic Force is a force that attracts certain metal objects (like iron and iron filings) towards a magnet.

• Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.

Atmospheric pressure:-

Atmospheric pressure is the force per unit area exerted against a surface by the weight of the air.

• Atmospheric pressure is also referred to as air pressure.

• Pressure at the top (surface). Atmospheric pressure is the pressure due to the air column over us and naturally, as we, move up in the air, the pressure decreases.
