  • What does Brownian motion prove?

    Brownian motion is the random (chaotic) motion of solid very small particles suspended in a liquid or gas. But what causes particulate matter to move? In the XIX century, a similar phenomenon was first described by the botanist R. Brown (this phenomenon was named after him). He watched as pollen randomly rushed in the water, then soot. But he could…

  • Atom vs. Molecule Comparison

     atom is the smallest, chemically indivisible particle of matter. All substances are composed of atoms. The fact that atoms exist was assumed by Democritus in the IV century BC. e. However, scientists were able to prove that atoms really exist only in the XIX century. There are more than 100 kinds of atoms. They differ from each other in their…

  • How to convert meters per second to kilometers per hour

     convert m/s (meters per second) to km/h (kilometers per hour), it is necessary to multiply this value by a factor of 3.6. For example, a body moves at a speed of 21 m / s. This means that it moves at a speed of 21 * 3.6 = 75.6 km / h. If you need to make a reverse translation (that…

  • Velocity is a vector quantity

     speed of a body can be defined as the distance that this very body travels per unit of time. In the SI system, it is measured in m/s (meters per second). However, in physics, velocity is considered as the distance that a body travels in a certain direction per unit of time. Since the direction is indicated, the velocity becomes a vector…

  • Relativity of mechanical motion

     mechanical motion of a body is a change in its position relative to other bodies in a selected reference frame, while a change in the position of the body occurs over a period of time. The reference system assumes the presence in it of a reference body, the origin (point) of reference on this body, which has a zero coordinate…

  • What is kinematics

    Kinematics, along with dynamics, is a branch of mechanics, which in turn is part of physics. Mechanics studies the mechanical motion of bodies, studies the ways of describing it, and also investigates the causes of mechanical motion. Kinematics, as a branch of mechanics, studies only the mechanical motion of bodies and the ways of describing it, regardless of the causes of this…

  • How are physical quantities measured?

    Physical quantities are quantitative characteristics of physical bodies and phenomena. Examples of physical quantities: body length, time interval, speed of movement of the body, body temperature, path traveled by the body. Different physical quantities are measured in different units of measurement. So the temperature is measured in degrees Celsius (° C), time – in seconds (s), distance – in meters…

  • What is a physical quantity?

    When studying physical bodies, phenomena, processes, it is necessary to somehow record their characteristics (properties, signs). At the same time, the characteristics can be not only qualitative (for example, the body falls, the gas expands, etc.), but also quantitative (at what rate the body falls, what volume the gas occupied, what mass the body has, what length of the trajectory,…

  • What is experience and observation?

    Observation and experience in physics are the two main methods of knowing the laws of nature. Man has long observed nature, its structure and phenomena, noted for himself various patterns, made conclusions and discoveries. Based on observations, assumptions about something often arise. These assumptions must somehow be confirmed, checked. In this case, experience comes to the rescue in physics. During…
