A rock is thrown straight up from the surface of the Earth. Which one of the following statements describes the energy
transformation of the rock as it rises? Neglect air resistance.
a) The total energy of the rock increases.
b) The kinetic energy increases and the potential energy decreases.
c) Both the kinetic energy and the potential energy of the rock remain the same.
d) The kinetic energy decreases and the potential energy increases.
e) Both the potential energy and the total energy of the rock increase.
Answer: d
Explanation:
Uuhhh I’m not good at explanations...
The kinetic energy decreases while the potential energy increases.
Option d is the answer because as soon as this ball gets thrown from the surface of the earth kinetic energy would be at its greatest.
we have
[tex]k=\frac{1}{2} mv^{2}[/tex]
The velocity is going to be minimized. As the ball is going up its velocity would be falling or decreasing due to gravity. [tex]k=\frac{1}{2} mv^{2}[/tex] would then have a smaller value. So kinetic energy is reducing/decreasing.
We have potential energy as u = m*g*h = 0. This is because the height is 0 as the ball is released. But as the ball goes up, the height would start to increase so the potential energy increases.
In conclusion as the ball is thrown straight from the earth, kinetic energy decreases and potential energy increases.

Which celestial object is found in the Kuiper Belt?
Answer:
Pluto, Pluto's Moons, and other asteroids
Explanation:
The Kuiper Belt is just another Asteroid belt but on the outside of the solar system and Pluto is a dwarf-planet, a large asteroid that is spherical like a planet and has the same characteristics as planets but way too small, that was found in the belt along with some moons. Asteroids were also found in the kuiper belt, a lot of them were really big asteroids. (The answer might just be pluto depending if it wants one object as the answer)

A The downward force exerted by the exhaust on the engine is greater.
B The magnitude of both forces is equal to zero acting in opposite directions.
C Both forces are equal in magnitude, but opposite in direction.

The magnetic forces makes a maglev train to float above the tracks because of the repulsion property and similar magnetic poles.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Box A isn't stable and will fall over since it's being pulled down and if you push it if nothing is around to secure it's movements. Box B is stable and will only side if nothing is around to secure it's movements. The mass of the boxes could also affect what would happen if you pushed the box, if Box B had a heavy mass it most likely wouldn't move. If Box A had more equilibrium and a heavy mass, It would have a better chance of not falling over.

If an object has kinetic energy, what must it be doing?
Answer:
It has to be moving in order for it to be kinetic energy and potential energy is when is not moving.
Answer:
The Object Must Be Moving!
Explanation:
Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.
