Thank you for your very in-depth reply. The main concern is whether the ball will travel further in the direction of the wall after rebounding, due to the spin. Your answer helped me realize the answer. The spin can only result in velocity along the wall as long as there is rotational energy...
Consider the case where a basketball rotating about its center of mass strikes a wall head-on. The velocity given it parallel to the wall due to the spin is caused by the friction between the wall and the ball as the ball is sliding against the wall during the collision. Friction is proportional...
I am coding a game in which I desire a projectile to undergo realistic curving when rotating while moving through the air. Let's consider the instance of a projectile that is initially moving forward while spinning clockwise along an axis placed vertically in it is center of mass. The object...

In this picture, you can see that the parts of the water facing away from the viewer reflect the sunlight from the position of the viewer up until where the sun would be reflected on unagitated water. Past this point in a direction...
I'm trying to understand the physics of reflection to better draw objects. Normally, you see the reflection of a light source on metallic surfaces where the angle of incidence can equal the angle of reflection. This should reflect an image of the source that is approximately equal in size to how...
I am manufacturing a plastic cube out of six flat, hard pieces plastic, of the same consistency as water bottle plastic. The top and bottom sides of the cube will be connected to the middle 4 panels by condom rubber. I need some kind of bendable plastic that can expand so that the cube can grow...
Thank you for your responses! I really like both ideas. You've helped me out quite a bit.
The more appropriate way to have stated my goal would have been:
"Overall, my goal is to use buoyant forces to move an object."
:)
I am working on a project in which I must move an object a moderate distance (left to personal preference) using buoyancy as the main mechanism of movement. I have a few ideas for how to accomplish this, but I am having major problems thinking about how to implement aspects of each. Below I...
