Question

Find the potential energy of an object of 10kg, When it is at the height of 6m abvoe the ground. Given g=10m/s square

Answer 1

Given

☞ Mass of body = 10 kg

☞ Height = 6 m

☞ g = 10 m/s²

To find

☞ Potential energy of body

Solution

From the given data we have ;

☛ Mass (m) = 10 kg

☛ Height (h) = 6 m

☛ Gravitational acceleration (g) = 10 m/s²

Now we will use the formula directly :-

⟼ Potential energy (P.E.) = m * g * h

Substituting values,

☛ P.E. = 10 × 10 × 6

☛ P.E. = 100 × 6

☛ P.E. = 600 J

☛ P.E. = (600/1000) kj

☛ P.E. = 0.6 kj

∴ Potential energy of object = 600 J or 0.6 kj

Some more informations :-

☞ Kinetic energy (K.E.) = ½ * m * v²

Where,

⟼ m = mass of object

⟼ v = Velocity of object.

Answer 2

QUESTION :-

Find the potential energy of an object of 10 kg , when it is at the height of 6 m above the ground .  Given g = 10 m/s².

SOLUTION :-

${\red{\sf{\underline{Potential\:\: Energy}}}}$

Potential energy is the energy stored within an object, due to the object's position, arrangement or state.

Potential energy = mgh

where,

m = mass of the object

g = acceleration due to gravity

h = height

Given-

→ mass (m) = 10 kg

→ acceleration due to gravity ( g) = 10 m/s²

→ height (h) = 6m

putting the above given values in the formula for potential energy....

Potential energy = mgh

                            =  10 kg × 10 m/s² ×  6 m

                            =  600 kg m² / s²

                            = 600 J

∴ Potential Energy of the object  = 600 J
