I used Serway Physics for Scientists and Engineers 6th edition for my undergrad degree. We used PhysicsNow, an integrated interactive tool with the Serway textbook. I found a copy that has an un-used code for PhysicsNow, but it looks like PhysicsNow no longer exists. Anyone here familiar with...

But PeroK made an interesting point above. "The second tells you the kinetic energy (KE) of an object of mass m moving with speed v. You can see that KE increases with the square of the velocity. Hence it takes four times as much energy to go from 1 to 2m/s as it does to go from 0 to 1m/s." So...

Multipart question: 1) How long would it take to travel to the moon from Earth at a constant 1 g acceleration? 2) How does fuel consumption work with constant 1 g acceleration or acceleration in general? I read that "it doesn't take a constant amount of energy to maintain a constant...
