When I initially met this problem, I was slightly confused because of the car analogy above. So the way to think about this is that your body and the car are separate, and just as the car starts going ...

So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibr...

We know that p=mv,

So Sophia travels at 7.2 m/s and she has a mass of 47kg so her p is: p=7.2 x 47=338.4 kgm/s

 Neesha travels with a velocity of -4.8 m/s and...

Water stays in the bucket for the same reasons that we stay in our seats when we do a loop on a rollercoaster. Another example is being driven round a roundabout and feeling a 'force' pushing you outwa...

As we know so far, c = f / λ. This equation comes from a much simpler version of speed = distance/ time. As the λ  (with units "m") can be seen as distance and the frequency (with units "...
