black hole

1. The black hole will suck away the clock's energy.

2. a. Black hole grow in mass by capturing nearby material.
b. If a fall into a suppressive black hole than my body remains intact, even as I cross the even horizon .
c. Light lass that pass close to the black hole get caught and can not escape.
d. black hole can spring around the axis.
e. The milky way center is as far as 28000 lightyears for us.

3.If I fall into a black hole, maybe I can not even escape, because of the it will took my energy, so if more you close to the black hole the more you will lose your energy.

summarize article energy

This articles is talking about laser energy meter. The laser energy meter is a power or energy meter is an important diagnostic tool to verify and quantify how your laser is performing. Regular measurement ensures your laser system is deliverying the specified amount of power or energy.
You can find out how your laser is performing:
1. Thermal, pyroelectric, photodiode, sensors.
2. wireless laser power meter.
3. high damage threshold.
4. high frequency.
5. NIST traceability.

Energy

Five ways that I think what is energy:
1.I think that energy is a thing that can kind of power for human.
2.I think that energy is a important thing in our life.
3.energy is a thing that can change the world.
4.I think energy is everything.
5.I think energy is that the food we ate and turn to energy.

Five ways that I search what is energy:
1. There are two types of energy
a. Stored (potential) energy
b. Working (kinetic) energy
2. Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen.
3. Energy is the capacity to do the work.
4. Energy can be change from one form to another but it can not be created or destroyed.
5. Energy is a power to change things.

3 fact about energy you aren’t sure are true :
1.We use energy that everything we do.
2. Just as there are many forms of energy, there are different ways to measure these forms. In science, work and energy are commonly measured in joules.
3. Energy equals Mass times the speed of Light squared.

so fun :D
