The weight of an object on a planet depends on not only its mass but also on its distance from the planest center. this table lists the weight of 80 kg on each planet in the solar system. uranus has more than 14 times as much mass as earth, yet the gravitational force is less. explain how this could be.

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

Where do magnetic lines of force enter earth?
