Question

Explain values of Newton, Pascal and Joule.

Answer 1

Newton is a unit of force, in order to accelerate 1 kg of mass at $1m/s^2$ we need 1 Newton force.
Pascal is a unit of pressure, the pressure is force per area, therefore, 1 Pascal is equal to 1 Newton force applied across 1 square meter of area.
Joule is the unit of energy, one joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter.
One joule is the equivalent of one watt of power radiated or dissipated for one second.
