### What energy can you use to go to the moon?

You wont need any energy but, you can still use a rocket.

### What source of energy is used by the rocket?

Depends on the rocket. Some rockets use solid fuel, some use liquid.

### Why do you think renewable energy is gaining attention in the US?

Renewable energy is gaining more attention because it is cheaper and better for the environment. The continued use of fossil fuels will only increase the amount of pollution in the air, water, and land.

### What formula do you use to determine the Gravitational potential energy of an object?

Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)

### What kind of energy does a rocket have?

It will have kinetic energy from its velocity, and potential gravitational energy from how high it is above the earth. If it is still being driven by a rocket engine, these amounts of energy will be increasing. If the engine has stopped it is in free flight, and will continue to rise until reaching maximum height and minimum speed, then it will start to pick up speed as it falls. The total energy will be constant once the engine has stopped. Of course in practice air resistance has some effect, some energy will be given up to the air in frictional heating.

### Why do you need water for a water rocket?

You could use other non compressible liquids. You really are using the air trapped in the rocket as the energy source. The water compresses the air to very high levels and then is pushed back out the enf of your rocket.

### Will solar energy die?

It is not very likely that solar energy will die out anytime soon. In fact solar energy has been steadily gaining popularity and many people are building off the grid houses that exclusively use solar energy.

### Why are you gaining weight really fast when you have had an IUD for a year and am not pregnant?

You will gain weight if the amount of energy you take in is more than the amount you use.

Rocket oil

### If a 2 kg mass has 40 j of potential energy with respect to the ground approx how far is it located above the ground?

Use the formula PE = mgh (potential energy = mass x gravity x height). Use 9.8 (which you might round to 10), for gravity.Use the formula PE = mgh (potential energy = mass x gravity x height).

### What is the potential energy of a book with mass of 2 kg and a height of 15 meters use pemgh?

The book's potential energy is 294 joules.

### When an 8 kg object increases its potential energy by 240 J how much has its position changed?

Just use the formula for potential energy: PE = mgh (potential energy = mass x gravity x height). Use 9.8 for gravity, replace the parts you know, and solve for the unknown position (height).
