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.
Answers
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.

Why would the crash affect the motion of the satellite? Write at least 1 paragraph and good vocab.
Answers
Answer:
The speed and direction of the two satellites would differ from each other cause the asteroids differ in size. The bigger one would have moved the satellite farther of track and go a bit faster than the other asteroid. The other one wont move it as far and the speed would not change by much.

Summarize the procedures you perform before, during, and after a lab investigation.
Answers
Answer:
Before Lab
At all times while in the lab area you must follow all classroom rules and behave in an appropriate manner or
you will not be allowed to participate in laboratory activities. You should come to class prepared with any
pre-lab assignments or instructions that have been given.
⋅ While working in the lab area safety goggles should be worn at all times.
⋅ All long hair should be tied back; open-toed shoes, baggy clothing, and loose jewelry should also be
avoided.
⋅ Know the location and proper use of all safety equipment (including fire extinguisher, fire blanket, firstaid kit, eye wash station, and sink) as well as classroom exits.
⋅ Food and drink are not allowed in the lab area.
⋅ Never work alone in the laboratory.
⋅ If there is an accident or a problem, immediately stop what you are doing and report it to your instructor.
During Lab
⋅ Before beginning any procedures, read through all lab instructions that your instructor has given.
⋅ If you do not understand the instructions or the procedures, ask for clarification.
⋅ Perform only procedures or experiments that have been assigned by your instructor.
⋅ Clean up all spills, including water, and messes immediately before proceeding.
⋅ Wear an apron whenever using acids, bases, or stains.
⋅ All solutions, chemicals, and specimens should be treated with care.
⋅ Never taste or smell anything in the lab. If instructed to smell something, use your hand to gently waft the vapors to
your nose.
Fire / Electrical Safety
⋅ Know the location and proper use of the fire blanket and fire extinguisher.
⋅ Never directly touch something that may be hot, use a hot mitt or tongs instead.
⋅ When heating, always point test tubes away from yourself or others.
⋅ Never use electrical equipment near water or moisture.
⋅ Extinguish all uncontrolled flames immediately and notify your instructor.
⋅ If a burn is received, immediately place the burned area under cold water and notify instructor.
⋅ Always make sure that all flames and electrical equipment are turned off when not in use.
Glassware / Sharp Object Safety
⋅ Never use glassware that is cracked or chipped (even if it does not leak).
⋅ When using a blade, never use a dull blade and always cut downward and away from your body.
⋅ If a cut is received, immediately wash the cut, apply pressure to stop the bleeding, and notify your
instructor.
⋅ Always dispose of broken glass in a glass disposal box and notify your instructor.
Chemical Safety
⋅ Know the location and proper use of the eye-wash, sinks, and chemical showers.
⋅ Know the location of sand or vermiculite in case of acid spills.
⋅ When diluting, always pour acids into water. Do not pour water into acid.
⋅ If a chemical is spilled on your person, immediately flush the area with water and notify the instructor.
⋅ Dispose of chemicals only as instructed in marked containers.
Biological Safety
⋅ Wear protective gloves when handling biological specimens.
⋅ If you come into direct contact with biological specimens or fluids, immediately notify your instructor.
⋅ Dispose of all biological cultures or materials containing live cultures in the proper biohazard bags.
After Lab
Before leaving the lab area, return all equipment to its proper place and make sure that your lab area is
cleaned up. After completing the lab wash your hands thoroughly with soap and water.

The kinetic energy of the pom-pom came from potential energy in the system.
How did potential energy gets stored in the spring/pom-pom system?
Answers
Answer:
I believe that the answer is that in physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.
The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
The potential energy stored in a spring is known as elastic potential energy. The elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
For example, when a spring is compressed it acquires potential energy which will be converted to kinetic energy of the object impacted by the spring.
The elastic potential energy of spring is given as;
[tex]U_x = \frac{1}{2}kx^2[/tex]
where;
k is the spring constantx is the extension of the spring.Thus, we can conclude that, the elastic potential energy of a spring is the energy stored in the spring due to its elastic nature.
