These are some of the 600+ videos that I have made covering the content for both Year 12 and Year 13, as well as the new Practical Endorsement. The molecule has a mass (m) and a velocity (v 1).Therefore the molecule has a momentum of mv 1.. momentum = mv 1. Any charged particles moving in a magnetic field will experience a force. Think about a single molecule moving towards the end of a box. Graphs of trigonometric functions. Circular Motion When an object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Think about a single molecule moving towards the end of a box. Now, consider all the molecules (N) in the cube and each of their x-component velocities (u1 u2 u3 . Thermal Physics . 1. all the molecules of a particular gas are equal, 2. collisions between molecules and their container are completely elastic, 3. collisions between molecules themselves are completely elastic, 4. the size of actual molecules is negligible compared to molecular separation, 6. extremely large numbers of molecules mean that statistical methods can be applied, 7. between collisions molecules move in straight lines at constant speed, 10. the time for each collision is negligible. Replacing these velocities with mean square velocities, the equation now applies for all molecules. Further Mechanics . These are free to download and to share with others provided credit is shown.

Superposition: Diffraction refers to the bending or spreading out of waves when they travel through a small opening or when they pass round a small obstacle.. The first step in understanding this theory is to appreciate the momentum change when a particle rebounds from a collision with a wall. When a charge passes through the power supply, it gains electrical energy. in the x-dir. Physics equation booklet a level. The Principle Of Superposition states that when two waves of the same kind meet at a point in space, the resultant displacement at that point is the vector sum of the displacements that the two waves would separately produce at that point. Full Video Index. As gas is heated it becomes less dense, i.e. So we can say that mean square velocity components are equal to one another.
