Question

write short note on inertia and mass

Answer 1

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.



mass:the quantity of matter in a body regardless of its volume or of any forces acting on it. The term should not be confused with weight, which is the measure of the force of gravity acting on a body.

Answer 2

Inertia - It is the property of a body by virtue of which it continues to be in the state of rest or of uniform motion unless it is acted upon by an external force.

Mass - Is the amount of matter (particles) constituting the body.
