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? What's the difference between average and instantaneous velocity? What is velocity measured in? What is the difference between momentum and velocity? What is the difference between constant velocity and acceleration?
What is velocity in physics? How do you determine the force on an object if there are multiple forces acting on it? What is range of motion in biomechanics? A force of 3 newtons and a force of 5 newtons act concurrently to produce a resultant of 2 newtons. The angle between the forces...
What is Velocity - Velocity is defined as the rate of change of displacement with respect to time. It is nothing but the speed at which an object moves in a particular direction. It is a vector quantity. It needs both magnitude and direction to represen

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 ) ...
like pushing, energy, speed, and even momentum. in physics, we have a very explicit definition for momentum. the momentum (at velocities not near the speed of light) is defined as the product of the mass and velocity of an object. this definition physicists (and textbooks) agree on. the...

In physics, motion is that phenomenon during which an object changes its position over time. Motion is calculated or described in terms of distance, velocity,displacement, acceleration, speed, and time. The motion of a body is observed by attaching a frame of regard to an observer and measurin...
