1 answer:

7 0

There are loads of similarities, but there are differences and that's what you want!

Speed- Is usually referring to how fast an object moves, it is calculated by space per unit.

Velocity- Refers to the rate at which said object changes position in a certain direction. Usually calculated by the displacement of space per unit.

SO it sounds the same, but simple answer Velocity deals with direction, and speed does not!

The power of an object is given by :

$P=\dfrac{E}{t}$

Here,

E is the energy required

t is time

The SI unit of power is Watts and the SI unit of energy is Joule. the commercial unit of energy is kilowatt per hour.

Option (1) : A kilojoule (kJ) is a unit of power is incorrect.

Option (2) : A gigawatt (GW) is a unit of energy is incorrect.

Option (3) : A watt (W) is a unit of energy is incorrect.

Option (4) : A kilowatt x hour per year (kWh/yr) is a unit of energy is incorrect.
