Newton's first law of motion states that. an object on the rest or motion is stay the same unless external force applied on it.
Answer:
the branch of science concerned with the nature and properties of matter and energy
<span>A gymnast with mass m1 = 43 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 115 kg and length L = 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end of the beam.
1)What is the force the left support exerts on the beam?
2)What is the force the right support exerts on the beam?
3)How much extra mass could the gymnast hold before the beam begins to tip?
Now the gymnast (not holding any additional mass) walks directly above the right support.
4)What is the force the left support exerts on the beam?
5)What is the force the right support exerts on the beam?</span>
It's b, because the more force an object it is given the harder it will be for it to slow down.
Answer:
The rate at which energy is transferred is called power and the amount of energy that is usefully transferred is called efficiency.
