As you might have guessed, the scalar (absolute value) magnitude of the velocity vector is the speed of motion. In calculus terms, velocity is the first derivative of position with respect to time. You can calculate velocity by using a simple formula that includes rate, distance, and time. ...
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 ...
Is speed a vector quantity? What is velocity in physics? Force A acts 2 N west and 3 N south. Force B acts 5 N west and 2 N north. What is the resultant of these two vectors in unit vector form? What is the direction of a vector when divided by a scalar quantity?
v = velocity of the body s = distance travelled (in the given direction) and t = time taken (to travel that distance) We know that the ‘Distance travelled in a given direction’ is known as ‘Displacement’. So, we can also write the definition of velocity in terms of ‘Displacement...
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...
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 ) ...
A linear wave number can also be described in terms of the wave's velocity (v) and frequency (f), as they relate to its wavelength. Velocity refers to the wave's speed and is measured in meters per second (m/s). Frequency refers to the number of wave cycles per second and is meas...
Velocity and speed are often used interchangeably in everyday language, however there is a distinction in physics. Velocity is a vector, which means it has magnitude and direction. It is calculated using displacement, which is the straight line distance from start to finish (...
