What type of energy do orbits have?

Answer: potential energy

ExplanationIn the case of circular orbits, this rate is one half of the gravitation at the orbit. This corresponds to the fact that for such orbits the total energy is one half of the potential energy, because the kinetic energy is minus one half of the potential energy.:

The smallest particle in the universe?
A grain of salt is small, but you can always make it smaller. Imagine cutting that grain of salt into two pieces. Now cut it again and again. Soon, you can't see the smaller pieces with your eyes, but the salt is still there. You finally cut the salt down to the very tiniest piece of salt there is. But even that tiny piece contains smaller particles. Those tiny particles are atoms. Atoms make up everything in the visible universe from galaxies to even yourself. Atoms are so incredibly small that you could line up 50 million in a row and the line would only be about 1 centimeter (less than half an inch) long. Still, scientists have found things that are smaller than atoms. And they are looking for more. If they find the smallest things in the universe, they'll better understand how the universe actually works. But it took some time before people discovered the world of the truly small.
The Universe Gets Smaller…
Grains of sand or dust were once the smallest things actually seen on Earth. By the 1600s, several inventions opened up brand new worlds to curious minds.
These included lenses that could make things look clearer and bigger. Another early invention was the microscope. Some people used the microscope to observe and write about the tiniest things they could see.
In the 1670s, a Dutch lens maker named Antonie van Leeuwenhoek built himself a microscope. It magnified things more than 200 times. Van Leeuwenhoek discovered a world of tiny living things that he called tiny animals. Van Leeuwenhoek figured they were about 1/38th the size of a grain of sand. Today we know that what he saw were bacteria, the smallest living things on Earth. But atoms are much, much smaller. You can't see atoms with an ordinary microscope.
…And Smaller
The idea that tiny, unbreakable particles make up everything that exists is more than 2000 years old. The Greek thinker Democritus called these particles "atomos." This is the Greek word for "uncuttable."
Scientists didn't return to the idea of atoms until the 1800s. At first, scientists thought atoms were tiny balls with some electrical charges inside. They also thought atoms were the smallest particles that existed.
But scientists soon began to wonder if atoms might be made of smaller things. In 1897, British scientist J. J. Thomson proved that they were. He ran experiments and discovered the electron. This tiny particle has a negative electrical charge and whizzes around inside the atom.

Different elements have different numbers of protons, neutrons, and electrons.
The Smallest Things—So Far
Scientists were soon discovering more inside the atom. Hiding in the atom's center is the tiny nucleus. (If an atom were the size of a racetrack, the nucleus would be about the size of a pea in the middle.) The nucleus contains two types of particles: protons and neutrons. Protons have a positive electrical charge while neutrons have no charge. They contain even tinier particles called quarks that are so unimaginably small that they have no internal structure. Quarks and electrons are the smallest particles found so far. Scientists call the smallest things they've found fundamental particles. Fundamental particles do not contain any smaller particles. Scientists use huge machines called particle accelerators to learn more about particles. These machines speed up particles so they can smash into each other. Then the scientists track the paths the particles leave when they hit. Scientists use accelerators to discover new particles.
Many scientists wonder why there are so many particles at all. Shouldn't there be just one "smallest thing" instead of many? The search goes on for the particle that is the one true building block of everything in the universe.

How did Antonie van Leeuwenhoek become involved with the study of small particles?
A He studied ideas from the ancient Greeks
B He made lenses that magnified things
C He was a biologist who studied bacteria
D He experimented with atoms and electrons
What happened as a result of J.J. Thomson’s discovery of the electron?
A Scientists developed more powerful microscopes
B Scientists learned that the atoms were empty inside
C Scientists continued to discover smaller particles
D Scientists decided taking apart atoms was dangerous

In a warehouse, the workers sometimes slide boxes along the floor to move them. Two boxes were sliding toward each other and crashed. The crash caused both boxes to change speed. Based on the information in the diagram, which statement is correct? In your answer, explain what the forces were like and why the boxes changed speed.

Box 1 has more mass than Box 2.
Box 1 and Box 2 are the same mass.
Box 1 has less mass than Box 2

If 2 objects are moved by the same force (F):
-The object with a smaller mass (m) has a larger acceleration (a)
-The object with a larger mass (m) has a smaller acceleration (a)

Calculated: force=mass x acceleration (F =M x A)

A box of mass (m) is pushed to cause an acceleration (a) on a frictionless ramp. The ramp has an angle θ.
What is the magnitude of the push force (F)?
