Velocity makes it possible to create timetables for travel, a common type of physics problem assigned to students. For example, if a train leaves Penn Station in New York at 2 p.m. and you know the velocity at which the train is moving north, you can predict when it will arrive at So...
What is velocity in physics? Physics: Physics is the study of matter, energy, and how matter and energy interact with one another. One of the ways that matter and energy interact is through the movement of objects. Answer and Explanation:1 ...
In physics, viscosity is often expressed using Isaac Newton's equation for fluids, which is similar to Newton'ssecond lawof motion. This law states that when a force acts on an object, it will cause the object to accelerate. The larger the mass of the object, the greater the force will...
What is velocity in physics? At what projection angle are the horizontal and vertical components of velocity are equal? What force affects vertical velocity in biomechanics? What is the horizontal component of a projectile's velocity? What is the vertical component of acceleration?
StudyingPhysics Topicscan lead to exciting new discoveries and technological advancements. Explain Why Speed and Velocity are Not Always Equal in Magnitude The speed of a car (or any other body) gives us an idea of how fast the car is moving but it does not tell us the direction in which...
From my understanding aa is the acceleration of point PP in reference frame SS and a′a′ (proper acceleration?) is the acceleration in frame S′S′, however, Wikipedia states that a=a′γ3a=a′γ3. How do I get that? Are t′t′ and v′v′ proper time and proper velocity respecti...
Physics is: More broadly defined, it is the general analysis of nature, conducted in a scientific order to understand how and why the universe behaves. 物理是: 从广义上说,物理是对自然的分析,用科学的方法研究宇宙的各种现象及其内在规律的学问。 Attending Rema International’s A-Level Physics 101 ...
Viscosity is the ratio of the shear stress to the velocity of the gradient. It can be computed with the following formula: Viscosity = ( force * distance between two layers of fluid ) / ( cross-sectional area * velocity of fluid) = ( F * d)/( A * v ) ...
Black holes have event horizons, which is a radius within which any object or light passing can't escape the black hole's gravity. The velocity required to escape this gravity is beyond the speed of light, a theoretical impossibility. Black holes are invisible and are calledblackbecause no li...
