Question

1. What is inertia? Write down the relation between mass and inertia?
2. What is acceleration? What would be the acceleration in a body
moving with uniform velocity and why?
and write dau​

Answer 1

Answer:

1. The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
2. The 'acceleration of a body' moving with uniform velocity will be zero as acceleration is defined as the “rate of change of velocity” per unit time. So if the body exhibit uniform velocity, then the rate of 'change of velocity' (dv = 0) will be zero. ... Thus the acceleration of the body will also be zero.

Answer 2

Answer:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing
