Yes. I think it is. If you are wasting your time staring at a wall, but you are enjoying it and still have work to do, you are wasting your time. Sometimes the point of wasting time is to, well waste time, but that doesn’t change the fact that you are wasting your time.
During this time, the total mechanical energy of the object remains constant.
Answer: Option C
<u>Explanation:</u>
The sum total of potential energy and the kinetic energy presented in the system is called mechanical energy. The total mechanical energy in the system, which represents the combined potential and kinetic energies, remains constant as long as the only force work at conservative forces, and mechanical energy is maintained on this principle.
For example, a gravity box in which we throw the ball straights up, and then leave the hand with a specific amounts of kinetic energy. In the first half of the track, there is no kinetic energy, but it has potential energy similar to kinetic energy that it had when that left our hand. When we catch that again, it has the same kinetic energy as when that left our hand. That is why gravity belongs to the category of conservative forces.
Answer:
Art
Explanation:
Polly's line is linear, while arts line is going up with constant velocity. There for art is going faster.
D) they will all hit the ground at the same time. In the context that there is no air resistance and each object is in free fall, then they will have the same acceleration rate.
Answer:
I think the answer must be A.
