What is a Moment in physics? (GCSE and A Level)

A moment is the turning effect of a force. The equation to calculate a moment is:Moment = Force (perpendicular to the pivot) x distance (from the pivot)For example, consider a horizon...

Newtons Laws of Motion explained (GCSE)

Newton`s laws of motion can be confusing, but they`re fundamental to understand and score full marks on lots of questions, so what are they and what do they mean?Newton`s First Law: A...

Current, Voltage & Resistance

Current, Voltage Resistance can be a tricky topic to get you head around. During my educational journey I have consistently used real world analogies to help understand unimaginable ...

Wave-Particle Duality

In PhysicsA wave, like light, can behave as either a wave or a particle.When light of a high enough frequency is shone on to a metal, electrons can be liberated from that metal. This ...

When a star collapses into a black hole, how long does it take for the star to overcome electron and neutron degeneracy pressure? And how long do those transitions themselves take?

Soft Collison is inelastic Collison

IntroductionOne of the interesting topic in physics is the mechanism of collision between different moving objects. In real life, we experience this principle on daily basis. Some of ...

UK audit of target volume and organ at risk delineation and dose optimisation for cervix radiotherapy treatments

Objective: Assessment of the extent of variation in delineations and dose optimisation performed at multiple UK centres as a result of interobserver variation and protocol differences...

Colour and Vision

Electromagnetic (EM) SpectrumThe Electromagnetic spectrum tells us what wavelengths and frequencies correspond to which types of radiation. The very small fraction of between UV (Ul...
