Choose the Right Physics Toy for Your Assignment: Tips from Miyu

AI Thread Summary
Miyu is seeking advice on selecting a physics toy for an assignment that requires explaining its physics principles and suggesting improvements. Suggestions include a toy car that shoots a ball straight up and a top that demonstrates gyroscopic precession. The PowerBall or GyroTwister is also recommended, with a suggestion to improve it by replacing the manual cord with an automatic starting device. Participants emphasize the importance of choosing a toy that clearly illustrates physics concepts to achieve a good grade. Overall, the discussion focuses on toy selection and potential enhancements for educational purposes.

Hello people!~

I have a latest Physics assignment in which I'm stuck! Can anyone advise me on how to go about doing it?

The instructions are as follows:

1) Select any Physics Toy.
2) Explain the Physics Principle(s) that is/are illustrated by the toy.
3) Suggest one or more improvements that can be made to the toy and design how the improvement(s) can be incorporated.
4) There is no need to manufacture the toy but a drawing of the improved design must be included.

What type of Physics Toy can I choose so that I can attain a good grade?

Love, Miyu.

How about that little car that goes at a constant speed and shoots a ball straight up (relative to itself) so the ball falls back into the little tube?

Do they still make tops these days? I suppose that demonstrates gyroscopic precession.
 
If not, you could always find a dradle...

I have the Powerball. You could make it better by implementing some other device to start it rather than that annoying cord you have to stick and pull. [:p]
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
