How about a massive catapult to replace the space shuttle

The poster suggested using a giant catapult to put things in space instead of rockets. Maybe he or she was kidding, or maybe not. But I have heard this idea before. Would it work? First, how do things ... determine the average force exerted on the ...The Walking Dead Shuffles Into Science Education With Bolts, Brains, and a Physics Quiz

So, time to ... would do. Kinetic energy is equivalent to one-half the mass of an object multiplied by the square of that object’s velocity, or: K e =(1/2)*Mass*(Velocity) 2 Once you have the energy of the bolt, you need to find the force it will impart ...How do you weigh a supermassive black hole?

After all, they’re like punctures in the fabric of space and time, and that has some inherent effects on our common sense. But maybe maddening would be a good word, too. Astronomers love black holes for the same reasons you do ... mass of the black hole ...How Do You Model the Earth-Moon-Sun System?

First, the gravitational force. How do you model ... Earth (I will assume the Sun doesn’t move). Use the force and the momentum to calculate the new momentum after a short time interval for both the Earth and moon. Use the momentum (and velocity) to find ...Do You Watch What You Say Online?
