Velocity can be defined as In physics, what does the formula v = wr normally represent? Why do we use velocity instead of speed in physics? The instantaneous velocity of an object is what? The rate at which velocity changes is called ...
The formula for velocity is given by velocity (v)=displacement (d)time (t)velocity (v)=time (t)displacement (d), where displacement is the distance covered in a specific direction. Far be it for us to criticize speeding tickets as a public safety tool (and a source of municipal rev...
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...
Anyone who has watched the movement of waves on water can understand the wave equation, one of the most basic relationships in physics. The two parameters you need to calculate a wave's velocity are its frequency -- the number of wave crests that pass a
What is viscosity? Learn the meaning and formula of viscosity with equations and examples. Understand the methods of measuring the viscosity of a...
This formula should be memorized because it will be used in solving numerical problems. Uniform Velocity (or Constant Velocity) If an object travels in a specified direction in a straight line and moves the same distance every second, we say that its velocity is uniform. Thus, A body has a...

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...
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. ...
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...
