Answer:
Explanation:
The center of mass lies on a line that joins position 4 of one start with position 4 of the other star. The shortest distance between these two points will produce the largest velocity. You are using F = m v^2/R
Small R = large force.
Large Force = increased speed.
The masses don't have any effect on the outcome: they remain constant.
The molecules of a solid vibrate faster so that they start spreading out to become a liquid. This energy makes them vibrate faster so the bonds between molecules can't interact all that well anymore creating more distance. The stronger the bonds between the molecules the higher the energy (temperature) has to be to get them away from each other. Hope I didn't confuse you too much!
Answer:
Explanation:
The work done on a particle by external forces is defined as:
According to Newton's second law 
. Thus:
Acceleration is defined as the derivative of the speed with respect to time:
Speed is defined as the derivative of the position with respect to time:
Kinetic energy is defined as 
:
