# Suggestions for any EE topics related to circular motion AND engineering physics

## Recommended Posts

Hello All,

I am currently in IBDP year 1. I really wanted some suggestions for a few EE questions related to a question, that includes both Engineering Physics and Circular Motion ( SUBJECT - PHYSICS ).

Can someone please suggest a RQ and a simple experiment that can be used to conduct the RQ?

Here are a few ideas for EE questions related to a combination of engineering physics and circular motion:

• RQ: How does the radius of a circular path affect the speed of an object moving in circular motion?

Experiment: You can set up a simple circular track using a piece of string or a circular object, such as a hula hoop. Place a small object, such as a ball, on the track and mark the starting point. Using a timer or stopwatch, measure the time it takes for the object to complete one revolution around the track at different radii. Calculate the speed of the object by dividing the distance traveled by the time it took to complete one revolution. You can repeat the experiment for different radii to see how the speed changes.

• RQ: How does the mass of an object affect its acceleration in circular motion?

Experiment: Set up a circular track as described above. Place a small object, such as a ball, on the track and mark the starting point. Using a timer or stopwatch, measure the time it takes for the object to complete one revolution around the track. Calculate the acceleration of the object by dividing the centripetal force (which is equal to the mass of the object multiplied by the velocity squared divided by the radius of the circular path) by the mass of the object. Repeat the experiment for different masses of the object to see how the acceleration changes.

• RQ: How does the angle of inclination of a circular path affect the speed of an object moving in circular motion?

Experiment: Set up a circular track as described above, but this time tilt the track at different angles of inclination. Place a small object, such as a ball, on the track and mark the starting point. Using a timer or stopwatch, measure the time it takes for the object to complete one revolution around the track. Calculate the speed of the object by dividing the distance traveled by the time it took to complete one revolution. Repeat the experiment for different angles of inclination to see how the speed changes.

I hope these ideas give you a good starting point for your EE investigation!
