How do you explain the fact that sometimes less work is done in a situation in which more force is used than in a situatio in which less force is used

Do the characteristics of a compound share the characteristics of the elements that make up that compound? Use water as an example in your explanation.

How would the tides on earth be different if the moon revolved around earth in 15 days

The potential energy of two atoms in a molecule can sometimes be approximated by the Morse function, U (r) = ARe (R-01.5 - 1) 2 where r is the distance between the two atoms and A, R, and S are positive constants with S << R.

One problem for humans living in outer space is that they are apparently weightless. One way around this problem is to design a space station that spins about its center at a constant rate.
