A wave could be transverse or longitudinal. We like to think in terms of whole waves. This is when a particle comes back to it's original position and direction of movement. For transverse waves, we can s...
The key is to realize that displacement, velocity and acceleration all vary sinusoidally, with the graph of each being displaced relative to the preceding one by 90 degrees; thinking about these three gra...
The photoelectric effect is light incident on a metal’s surface causing the spontaneous emission of electrons. The classical wave theory of electromagnetic radiation predicted the kinetic energy of emitte...
For an object to stay in a steady orbit; F=mv2/r where: F is the force on the object towards the centre of the orbit, m is the mass of the object, v is the radial velocity of the object, and r ...
First law: Unless acted upon by a force, a object either remains at rest or moves at a constant speed.Second Law: Force=Mass*AccelerationThird Law: For every action there is an equal and opposite reaction...
