Question

which bird on the wire has the more potential energy?Prove your answer using the formula of potential energy​

Answer 1

Answer:

Bird with 120 gram weight has more potential energy because, the formula of potential energy is mass×Gravitational acceleration×height. The last two are same but mass is different that's why bird 1 has more potential energy

Answer 2

Answer:

Bird whose weight is 120g has more potential energy.

Explanation:

Given:

• Weight of first bird (m1) = 120g
• Weight of second bird (m2) = 40g

To find:

• Which bird on the wire has the more potential energy?

Solution:

According to the question,

Both birds are sitting on the same wire, so we can say that the height (h) at which both the birds are placed are equal.

Potential energy can be given by the following formula:

e = mgh

where,

• e is representing the potential energy of object.
• m is representing the mass of the object.
• G is representing the gravitational acceleration
• h is representing the height at which the object is placed.

Now, at first we will find the potential energy of the first bird, which will be given by,

e1 = m1gh

Here, m1 = 120

So, we can say that the potential energy of the first bird is 120gh.

Now, potential energy of the second bird will be given by,

e2 = m2gh

Here, m2 = 40

So, we can say that the potential energy of the second bird is 40gh.

Now, on taking the ratios of potential energies of both the birds, we get,

$\frac{e1}{e2} = \frac{120gh}{40gh}$

Therefore, e1 : e2 = 3 : 1

e1 is equal to 3 times of e2. It means the potential energy of the first bird is 3 times of the potential energy of the second bird.

So, the potential energy of the first bird is greater than the potential energy of the second bird.

Therefore, the bird whose mass is 120 g has more potential energy.

Hence, proved.

Formula used:

• e = mgh
