are atoms in constant motion?

Atoms and molecules are always in motion. Sometimes this motion is easy to observe, such as when you see evidence of molecules in air bouncing dust particles around. ... However, the atoms and molecules in a table are constantly moving—by shaking back and forth, or by twisting—even if they stay in the same place.

what is the acceleration of a body moving with constant velocity? Acceleration is zero when the body is moving with a constant velocity.

An ideal gas has identical particles of zero volume, with no intermolecular forces between them. The atoms or molecules in an ideal gas move at the same speed. ... When pressures are very high and the molecules are compressed, the volume of the molecules becomes significant.

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements.

Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

Yes,a body can have zero velocity ,and constant acceleration. A body will have zero velocity when in a circular motion, i.e the body comes back to its initial position. ... Since the motion is circular,there will be a constant acceleration.

Constant acceleration:change in the velocity by same amount each second. Uniform acceleration:a body is said to be in uniform acceleration,if it travels in a straight line and its velocity increases by equal amounts in equal interval of time.

No, atoms are not living things. Whether something is alive depends on its ability to do things like grow, respire and reproduce. These are obviously only things that complicated structures can do, not atoms.

If so, give an example. Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration, i.e. it is moving at constant velocity. For example, a puck sliding along a horizontal plane of ice after being hit with a hockey stick.

If you travel with a constant acceleration, your velocity is always changing, but it's changing by a consistent amount each second. The acceleration due to gravity on the Earth has the constant value 9.8 m/s2, so you can imagine this like dropping something from a skyscraper.

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. ... The charge on the proton and electron are exactly the same size but opposite.

Atoms represent the smallest pieces of matter with constant properties, and are referred to as the basic unit of matter. However, scientists have discovered that atoms are not the smallest particles in nature. Despite their minuscule size, a number of much smaller particles exist, known as subatomic particles.

No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. ... The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.

Kinetic Energy and Molecular Speed Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). Kinetic energy, for an individual atom, can be calculated by the following equation where m is the mass, and u is the speed. Ek = 1/2 mu2.

Molecular motion for the particles in a solid is confined to very small vibrations of the atoms around their fixed positions; therefore, solids have a fixed shape that is difficult to change. Solids also have a definite volume; that is, they keep their size no matter how you try to change them.

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. ... Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.
