It is derived because you can not determine the rate of speed it will always be because any amount of sheer force can be applied to it.
Answer:it causes the moving object to slow eventually stop
Explanation:
When object travels with uniform velocity, no force acts on it. hence , yes.
Answer:
3.78 m on the left side of the seesaw
Explanation:
The net torque in this situation is zero, so the torque from each side of the pivot point must balance each other out:
(50.0 kg x 10.0 m/s^2)(3.4m) = (450 N) r
Solve for r, and you get 3.78 on the left side.
Hope this helps!
Mass and weight are different. Mass is the measurement of how much matter an object has, while weight deals with the pull of gravity. For example, an astronaut floating in space is weightless, due to the limited influence of gravity. But he will still have mass, that is because mass and weight are different :)
