Physics Measurement Quiz

Some students observe drops of water falling from a tap that leaks, as shown in Fig. 1.1. The students measure the time for 50 drops to fall from the tap. The time for 50 drops to fall is 20 s. Calculate the average time between two drops falling.

The students collect some drops of water. (i) The students measure the volume of the water they collect. State the term for the equipment that is suitable for measuring the volume accurately.

In a similar experiment, another student collects 0.21 kg of water. Calculate the weight of this water.

Four students P, Q, R and S each attempt to measure the time period (the time for one complete oscillation) of a pendulum. The arrows in Fig. 2.1 show the movements of the pendulum that each student times. State the student who has chosen the correct movement for one period of a pendulum.

Another student uses a stopwatch to measure the time taken for 50 periods of a pendulum. Fig. 2.2 shows the time taken on the stopwatch. Calculate the time for one period of the pendulum. Give your answer to 3 significant figures.

The student measures the displacement of the pendulum bob from its rest position. The displacement is 16.5cm, as shown in Fig. 2.3. State the displacement in millimetres.

A student measures the length of the sides of a metal cuboid using a 30 cm ruler. State the measured lengths of the following sides. (i) Side A in Fig. 1.1

Calculate the volume of the metal cuboid. Give your answer in cubic metres.

The student measures the mass of the metal cuboid on a scale. State the reading for mass. Give your answer in kg.

Use the information in the table to identify the type of metal which the cuboid is made of.
