Physics Gravity Car Research Help

AI Thread Summary
For the physics assignment on building a gravity car, focus on researching concepts such as gravitational potential energy, kinetic energy, torque, mechanical friction, and air resistance. Understanding these principles will help explain the car's motion, including how it starts, accelerates, and stops. Instead of using negative keywords in searches, look for general information on gravity cars and their mechanics. Consider exploring educational websites, physics textbooks, and online resources for more comprehensive insights. Clarifying the car's intended performance goals, such as distance or speed, will also guide your research effectively.

I know I am abandoning the template but my question doesn't really fit in that template so sorry.

Anyway for my Physics Assignment I have to do an EEI on a gravity car that I have to build, see this image for more help: http://seniorphysics.com/physics/gravity_car.jpg. Anyway I am struggling at the research bit. I have no idea what to research.

What should I be researching, what should I be looking for in research and where should I be researching(eg Google or library etc)?

I have tried 'physics of "gravity car" -anti -zero' in Google with no such luck. I just need some guidance.

Thanks in advance.

Do you understand these concepts?

gravitational potential energy
kinetic energy
torque
mechanical friction
air resistance

Then you should be able to work out why the car will start, accelerate, slow down, and stop.
 
For a start you are thinking of the entirely wrong thing if you are putting anti or zero gravity into google.

How is the car driven in that picture do you think? (hint look at what is attached to what)
 
No I put don't include. (-) means don't include.
 
Fair enough, it would have been less confusing to just not put anything rather then saying what you didnt look at as then we would know you were on the right track. :P

But anyway...

How do you think the car works in the picture?
 
Is the car supposed to go a long distance? Maximum velocity? Drag race?
 
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...
