When a conductors carrying current is placed in a magnetic field, the field exerts a force on the conductor and vice versa. Fleming's left hand rule is a tool that you can use to help work out the relativ...
When a particle moves in circular motion, the resultant centripetal force acts radially towards the centre of the circle. Since there is a force there must be an acceleration on the particle due to Newton...
Work done = Force in direction of motion (horizontal in this case) x distance. Force in direction of motion is 120 x cos(26) (draw a diagram to help visualise this) and distance is 5. Therefore work done ...
Firstly, all waves transfer energy without transferring matter (particles).
Waves usually consist of particles vibrating in a particular direction, but not necessarily in the same direction as the...
Firstly, particles can be split up into to main categories: hadrons and leptons.
Hadrons interact with the strong force and are made of quarks. Leptons don't interact with the strong force and are ...
