Determine an approximate value for the acceleration of free fall using a tennis ball, metre ruler and a stopwatch.

Drop the ball from a given height that is measured with the ruler and measure the time it takes for it to reach the ground using the stopwatch. Use the appropriate SUVAT equation of motion: we have a heig...

How do I convert between eV and J

eV means electron volt - that is, it the amount of energy required for an electron to travel down (or up) a potential gradient with a potential difference of 1V. This energy, known as the work done, W, is...
