## Velocity in Physics – Meaning, Measurement, & Calculation (RP6)

In RP2, we got a feel for the meaning of speed and velocity. Now is the time to define these little beasties more carefully. We’ll start by doing something weird: we’ll constrain movement to one dimension: that’s motion in a straight line, either forward or backward. If we can describe 1-dimensional motion, then maybe it

## Phase Velocity versus Group Velocity: Wave Dispersion

Suppose we add several waves together to create a new wave. If we change the amplitudes of the waves, the resultant wave also changes. The waves can have different wavelengths. The bottom wave has a slightly different wavelength than the other two. As we move the two other waves, notice how the sum of all

## Average Velocity | Physics

If I tell you that an object is moving in a straight line with the speed of 50 km/h are for one hour and then it moves at the speed of 25 km/h for one hour and ask you to study the motion, ask you to understand the motion of this object. It will not

## Physics 2100 – CSULA – Video #2

Welcome to Physics 2100 at Cal State LA I’m your professor Dr. Bijan Berenji. This is video 2 on kinematics, August 2016 Introduction We embark on our study of kinematics by exploring concepts of position, velocity and acceleration. Will think of these quantities of functions of time may be related to each other using calculates.

## DERIVE Equations of Motion | A Level Physics

you must be familiar with the equation speed is distance over time but this equation is only applicable to a travelling object with no acceleration it is no good for when we need to consider acceleration. There are four equations to describe an object traveling with constant acceleration. For all these equations u represents initial
