Nov 5, 2024 · Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. Its scope of study encompasses not only the behavior of objects under the action of forces but also gravitational, electromagnetic, and nuclear force fields.
What’s the matter? Matter is the material substance that constitutes our whole observable universe, and it is the subject of study of physics. Physics, the basic physical science, studies objects ranging from the very small (using quantum mechanics) to the entire universe (using general relativity). It deals with the structure of matter and ...
Nov 5, 2024 · Newton’s laws of motion, three statements describing the relations between the forces acting on a body and the motion of the body, first formulated by English physicist and mathematician Isaac Newton, which are the foundation of classical mechanics.
Oct 30, 2024 · gravity, in mechanics, the universal force of attraction acting between all bodies of matter. It is by far the weakest known force in nature and thus plays no role in determining the internal properties of everyday matter. On the other hand, through its long reach and universal action, it controls the trajectories of bodies in the ...
Oct 30, 2024 · Friction, force that resists the sliding or rolling of one solid object over another. Frictional forces provide the traction needed to walk without slipping, but they also present a great measure of opposition to motion. Types of friction include kinetic friction, static friction, and rolling friction.
Sep 23, 2024 · Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. The units in which work is expressed are the same as those for energy.
Sep 25, 2024 · In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Oct 22, 2024 · density, mass of a unit volume of a material substance. The formula for density is d = M / V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Oct 26, 2024 · BCcampus Open Publishing - Conservation of Momentum. Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton’s second law of motion states that the time rate of change of momentum is equal to the force acting on the particle.
Oct 26, 2024 · Christian-Albrechts-Universität zu Kiel - Faculty of Engineering - Young's Modulus and Bonding. Young’s modulus, numerical constant that describes the elastic properties of a solid undergoing tension or compression in only one direction.
