What type of energy is useful in light?
Light is energy. Light is made of massless particles called photons that travel at the speed of light. Photons at a given frequency carry energy equal to the Planck constant times the photon's frequency.
How long would it take for a spaceship to reach the earth from the moon?
It took Apollo 11 three days to travel from Earth to the moon.
What happens if you step outside of a spaceship traveling at light speed?
Well first of all, you don't. No object that has any mass when it's sitting still will ever travel at light speed. To answer your question in general: If you're sitting inside a spaceship, sipping a cup of coffee and surfing the web, and you decide to take a break from your back-breaking labor and step outside for a few minutes, then the moment you're outside, you continue traveling at the same speed and in the same direction that the ship was when you let go of it. If the ship is traveling with constant velocity ... constant speed in a straight line ... then you seem to float motionless next to it, because your speed and direction are exactly the same as the spaceship's. If the ship is accelerating, then you keep the speed and direction that you and it had when you let go, and the ship goes on its own merry way, leaving you behind, beside, or ahead.
Which waves travel the fastest?
The light wave, which is electromagnetic energy, is the fastest wave. The speed of light, which is a physics constant, is the speed of light in a vacuum, and no object with mass can be accelerated to this speed.
Would Kinetic energy be stronger on a tall hill or a lower hill?
The height of the hill does affect the kinetic energy directly. The formula goes like this : Etotal= Ekinetic energy+Egravitational potential energy Ek= 1/2(mass)(velocity2) and Eg= (mass)(gravitational constant 9.8)(height) So as you get closer to the ground, the kinetic energy increases while the gravitational potential energy decreases, but the total energy remains the same throughout. Therefore, the higher you are, the more energy you are going to gain as you travel down the hill.
What energy sources are used in space travel?
You need fuel for your spaceship.

How much faster does a spaceship travel than the orbit that it is in?
Usually the spaceship will turn off its engines soon after takeoff; therefore, it will travel precisely at the "speed of its orbit", most of the trip.
