What is the easiest experiment to do on a physics project?

The easiest experiment to do for a physics project will depend on your available resources and the level of complexity you’re comfortable with. Here’s a simple experiment that you can consider for your physics project:


Investigating the Effect of Mass on Pendulum Swing


  • String or thread
  • Small weight objects (e.g., washers, paperclips)
  • Stopwatch or timer
  • Ruler or measuring tape


  • Tie one end of the string/thread to a fixed support (such as a ring stand or a doorknob) so that it hangs freely.
  • Attach a small weight object (e.g., a washer) to the other end of the string/thread.
  • Measure the length of the string/thread from the support to the center of the weight. Record this length as the “pendulum length” (L).
  • Displace the weight slightly to one side and release it, allowing it to swing back and forth like a pendulum.
  • Use a stopwatch or timer to measure the time it takes for the pendulum to complete one full swing (from one extreme to the other and back to the starting point). Record this time as the “period” (T).
  • Repeat the experiment two more times and calculate the average period.
  • Now, vary the mass of the weight object while keeping the length of the string/thread constant. You can do this by adding or removing small washers or paperclips.
  • Repeat steps 4-6 for each different mass of the weight object, recording the period for each trial.
  • Plot a graph with the mass of the weight object (independent variable) on the x-axis and the period (dependent variable) on the y-axis.
  • Analyze the data and observe any patterns or trends. Note the relationship between the mass and the period of the pendulum swing.


This experiment investigates the effect of mass on the period of a pendulum swing. By changing the mass while keeping the pendulum length constant, you can observe how mass influences the time it takes for the pendulum to complete one swing.
