First Rule: An object will remain at rest or in a uniform state of motion unless that state is changed by an external force. Second Rule: Force is equal to the change in momentum (mass times velocity) over time. In other words, the rate of change is directly proportional to the amount of force applied.

What is the best physics definition?
Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity.
What is the easiest definition of physics?
Definition of physics 1 : a science that deals with matter and energy and their interactions. 2a : the physical processes and phenomena of a particular system. b : the physical properties and composition of something. Example Sentences Phrases Containing physics Learn More About physics.
What are the 5 primary terms of motion?
Any object that moves from one point to another is considered in motion. Motion is described using different descriptors such as distance, displacement, speed, velocity, and acceleration.
What is the longest word in physics?
In 45 letters, “Pneumonoultramicroscopicsilicovolcanoconiosis” describes “a disease caused by the inhalation of very fine silica dust, causing inflammation in the lungs.” However, indignant, long-winded scientists everywhere have a legitimate reason to dispute science’s supposed ownership of the term.
What are energy words?
What’s another word for energy in physics?
Some common synonyms of energy are force, might, power, and strength.
What are the 7 branches of physics?
- Mechanics. Mechanics is the branch of physics that deals with the motion of an object without or with the reference of force.
Is physics easy or hard?
Students and researchers alike have long understood that physics is challenging. But only now have scientists managed to prove it. It turns out that one of the most common goals in physics—finding an equation that describes how a system changes over time—is defined as “hard” by computer theory.
Who is the father of science?
Albert Einstein called Galileo the “father of modern science.” Galileo Galilei was born on February 15, 1564, in Pisa, Italy but lived in Florence, Italy for most of his childhood. His father was Vincenzo Galilei, an accomplished Florentine mathematician, and musician.
What is the original name of physics?
Physics was known as natural philosophy until the late 18th century.
What is the language of physics?
Although mathematics has long been regarded as the “language” of physics, the connections between these independent disciplines have been far more complex and intimate than previous narratives have shown.
What are the 11 types of motion?
- Oscillatory Motion.
- Rotational Motion.
- Translational Motion.
- Periodic Motion.
- Circular Motion.
- Linear Motion.
- Uniform Motion.
- Non-Uniform Motion.
What are the 4 basic types of motion?
What are the 4 types of motion in physics?
In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating.
What does F mean in physics?
F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. W = mg. W = weight. m = mass.
What are the units in physics?
- metre (m) – unit of length.
- kilograms (kg) – unit of mass.
- second (s) – unit of time.
- ampere (A) – unit of electrical current.
- kelvin (K) – unit of temperature.
- mole (mol) – unit of the amount of substance.
What is unit of velocity?
The SI unit of velocity is metre per second (m/s). Alternatively, the velocity magnitude can also be expressed in centimetres per second (cm/s).
What is the oldest word?
According to a 2009 study by researchers at Reading University, the oldest words in the English language include “I”, “we”, “who”, “two” and “three”, all of which date back tens of thousands of years.
What is the shortest word?
The shortest word is a. Some might wonder about the word I since it consists of one letter, too. In sound, a is shorter because it is a monophthong (consists of one vowel), while I is a diphthong. Both do consist of one letter in the English writing system, and in most fonts I is the narrowest letter.
What is the Greek word of energy?
The word “energy” comes from the Greek enérgeia. Developed by Aristotle (384 BC − 322 BC), enérgeia has no direct translation to English, although it is frequently described as “being at work”.
What is the Greek meaning of energy?
Energy is from Greek energeia “activity, operation,” from energos “active, effective,” from en “in” plus ergon “work.” Specialized senses of the word energy include the power that comes from sources such as heat or electricity, and the ability of sources such as heat or light to do work.
