Error analysis/mechanics help appreciated

    State and justify the techniques you would use to reduce the errors of the following. Each explanation should show a clear understanding of why the technique is relevant in the particular situation.

    1. Measure the time it takes for a ping pong ball to drop from a height of 50 cm and bounce 3 times.

    2. Measure the voltage across a resistor. Imagine you are provided with a connected series circuit of battery in holder, resistor, lamp, contact switch, 2 connecting wires, and a multimeter.

    3. Measure the mass of a washer if you are provided with 5 washers and a digital balance.

    4. Find the leg room under the bench (distance from the ground to the bottom of the metal strip under the bench top). You are provided with a metre ruler.

    Probably the best approach would be for you to tell us where you think which kind of errors would come from and how you would go about dealing with them. Then we'll see how you are thinking about it and can redirect you.
