describe what happens in terms of energy when you blow up a ballon and release it without trying its neck​
const2013 [10]

Answer:

The answer is below

Explanation:

When a gallon is blown the air energy is saved as potential energy which is compressed inside the balloon. However, when the balloon is released without trying its neck, the air energy quickly turned to kinetic energy, in which the air energy keeps moving as the balloon float around the space.

Hence, in short, what happens in terms of energy when you blow up a balloon and release it without trying its neck​ is that the air energy moves from potential energy to kinetic energy.

Group the labels according to the type of force they describe<br> Contact, no contact or both
Jobisdone [24]

We can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.

<h3>What are some examples of these forces?</h3>

There are many everyday examples to be used to describe each of these forces. A very common no contact force is gravity. The Earth's gravity exerts a force on all things near the planet, but it does not need to be in physical contact to exert this force, thus making gravity a no contact force. An example of a contact force would be if you were to push another person. You are exerting a force that <u>requires </u>physical contact.

Therefore, we can confirm that a contact force would be one in which physical contact is needed, while a no contact force does not require contact.
