Calculating Centripetal Acceleration Centripetal acceleration is defined as: The acceleration of an object towards the centre of a circle when an object is in motion (rotating) around a circle at a...
What Causes Centripetal Acceleration? Velocity and acceleration are both vector quantities An object in uniform circular motion is continuously changing direction, and therefore is constantly cha...
Angular Speed Any object travelling in a uniform circular motion at the same speed travels with a constantly changing velocity This is because it is constantly changing direction, and is therefore ...
Radians & Angular Displacement In circular motion, it is more convenient to measure angular displacement in units of radians rather than units of degrees The angular displacement (θ) of a body ...
Quark Composition: Protons & Neutrons Protons and neutrons are not fundamental particles. They are each made up of three quarks Protons are made up of two up quarks and a down quark Neutrons ar...
Fundamental Particles: Quarks Quarks are fundamental particles that make up other subatomic particles such as protons and neutrons Protons and neutrons are in a category of particles called hadrons...
Neutrino Emission An electron neutrino is a type of subatomic particle with no charge and negligible mass which is also emitted from the nucleus The anti-neutrino is the antiparticle of a neutrino ...
Alpha, Beta & Gamma Particles Some elements have nuclei that are unstable This tends to be when the number of nucleons does not balance In order to become more stable, they emit particles and/o...
Nucleon & Proton Number The atomic symbol of an element is used to describe the constituents of the nuclei An example of this notation for Lithium is: Atomic symbol for Lithium When given an at...
