For a simple pendulum (at the surface of the earth) the period of the pendulum, T, is 

where L is the length of the pendulum and g is the acceleration due to gravity.

According to this law, if you took a pendulum to the surface of a planet which had double the value of g (and kept the length of the pendulum the same) what would happen to the period of the pendulum?

The ideal gas law is:

PV = nRT

where P = pressure of the gas, V = volume of the gas, T = the temperature of the gas, and you can consider n and R as constants.

For a container of constant volume, you vary the pressure and measure the resultant temperature. You then plot temperature vs pressure (with temperature on the vertical axis and pressure on the horizontal axis). From the ideal gas law, you would expect a straight line. What would you expect to be the gradient of that straight line?

Which of the following statements are correct?

You use a video to create a graph of the position of Usain Bolt from the starting line vs time from the start of the race, and you get the graph shown below.

You use the graph to calculate what his position might have been at a time of 10 s. This process is known as:

Which of the following graphs depict a linear relationship? (Select all that apply)

You boil a kettle of water. Once the water has reached boiling point, you turn off the kettle and you measure the temperature of the water at time intervals of 1, 2, 3, 4, 5 and 6 minutes from when it reached boiling point. You plot a graph of the temperature of the water vs the time since the water boiled. What is your "independent" variable?

You measure the time it takes for a ball, starting at rest, to fall to the ground from heights of 1, 2, 3, 4, 5 and 6 m. You plot a graph of the initial height of the ball from the ground vs the time taken for the ball to reach the ground. What is your "dependent" variable?

Match the propotionality to the shape of the graph.

If y = √x, plotting which of the following would give a straight line graph?
