Question

2.Write the formula associating energy with power 

Answer 1

Answer:

$Power = \frac {mgh}{time}$

Explanation:

2. Power can be defined as the energy required to do work per unit time.

Mathematically, it is given by the formula;

$Power = \frac {Energy}{time}$

3. Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

$P.E = mgh$

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

4. Substituting the equation in 3 into equation in 2 above, we have;

$Power = \frac {mgh}{time}$
