Momentum (p) can be defined and calculated using the following equation: Where m is the mass and v is the…
The work-energy principle states that: The net work done on an object is equal to the change in kinetic energy…
Standing waves are also referred to as stationary waves. When a wave transfers energy from one point to another it…
Wave interference occurs when two waves, both travelling in the same medium, meet. Depending on the phase of the waves…
Electrical current is the rate at which charged particles flow, usually through a conductor. The drift velocity is the average…
Cells and batteries (both sources of electricity) have resistance, this resistance is called internal resistance. Internal resistance is caused by…
If components in a circuit aren’t connected consecutively and are on different branches of the wire they are said to…
If components in a circuit are connected consecutively, without any branches in the wiring, they are said to be connected…
Light waves are often referred to when discussing reflection, refraction and diffraction. However, these behaviours also apply to other waves…
Electronvolts are a unit particularly useful in atomic and nuclear physics and can be defined as follows: Electronvolt (eV) –…
