Physics Experiments: Constructing Investigation Design Report

Click For Summary
A user seeks assistance in finding a simple experiment to help construct an investigation design report. Suggestions include building a catapult using arrows and bungee cords to explore concepts like velocity and kinetic energy, though the complexity may be a concern. Another proposed experiment involves heating water in two differently sized pots to compare heating times and analyze the impact of pot dimensions. Participants emphasize the importance of choosing a subject of personal interest for the experiment. Overall, the discussion focuses on selecting accessible experiments that align with the user's goals.

can anyone help me find a simple experiment that i would be able to use to guide me to construct an investigation design report?

You could build a catapult out of arrows and bungee cords. Set the stopping point at some angle. Then calculate expected velocity, kinetetic energy, etc... Maybe the angular velocity, momentum etc... of the swining arm...possibly coefficient of friction, stuff like that.

I don't know if this is too simple or advanced...


Fun nevertheless.
 
cheers for the suggestion, i think it may be alittle complex for what I am trying to do. have you got any others??
 
Welcome to PF, Jstark11. It would probably be to your advantage to choose a subject that you enjoy and pick an experiment that is within that area. What are your interests?
 
How about you take two pots, one wider than the other, and fill them with the same amount of water (making sure the water's all at the same temp.) Put a pot on a burner and heat it up until it boils; every minute or so record the temperature with an oven thermometer or something. Do the same with the other pot some time later in the day (after the burner's cooled down). See if the dimensions of the pots have anything to do with how quickly the water heats up.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
