What is true of both gravity and magnetism?

Both are dependent on mass.

Both forces can act without objects touching.

Both forces are directly proportional to the distance between the objects.

Neither is a fundamental force of nature.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
