Question

1. Define the Following:
i) Power
ii) Inertia​

Answer 1

Answer:

Inertia is the resistance of any physical object to any change in its velocity. ... The vis insita, or innate force of matter, is a power of resisting by which every body, as much as in it lies, endeavours to preserve its present state, whether it be of rest or of moving uniformly forward in a straight line.

Answer 2

Answer:

1) In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity.

SI unit: watt (W)

In SI base units: kg⋅m2⋅s−3

2) Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.
