This is a past exam question from an A level paper for OCR Physics B.We know that in one second, a volume of water (V), travelling at 2.5 m/s is passing through an area of 500 metres squared in one second...
To answer this question you must use the magnetic field "Right Hand Rule". We know that if a charged particle enters a magnetic field it will experience a force perpendicular to both ...
To understand this question, it is important to know that velocity has both a direction and a magnitude. The magnitude can be expressed by the unit m/s, however the direction is expressed by a vector. ...
Acceleration is a change in velocity over time. Velocity is different to speed, because it has a direction (for example a car moving at 10 mph along a road heading north will have a greater ve...
a) Calculate the magnitude of the total momentum of the trucks.
The momentum (p) is the mass (m) of an object multiplied by its velocity (v).
p = m x v
