I am just asking this out of curiositymfb said:This sounds like a homework question.
Our body/arms and the balls potential energy?mfb said:What has energy before you hit the ball?
mfb said:The ball doesn't change its height, no relevant potential energy involved.
Initially the energy is somewhere in you, sure, but I was more thinking about the situation directly before you hit the ball - with the moving cue.
Does the cue have potential energy (Which then becomes kinetic energy)?mfb said:with the moving cue.
What form of potential energy are you suggesting? Elastic, gravitational, electric, spiritual ...?Kaushik said:Does the cue have potential energy (Which then becomes kinetic energy)?
I was suggesting 'gravitation potential energy' as it is kept at some height from the Earth's surface.haruspex said:What form of potential energy are you suggesting? Elastic, gravitational, electric, spiritual ...?
What makes the cue move, in your experience?
Yes.Kaushik said:So is it the energy in our body which transforms into kinetic energy of the cue, later into kinetic energy of the ball?
After surfing on the internet for a while, I learned that it is the chemical energy in our body (stored in the mitochondria due to the food we eat) which transforms into mechanical energy of the muscles.haruspex said:Any thoughts on the transformations within the body?
Yes, that explanation skips a step.Kaushik said:After surfing on the internet for a while, I learned that it is the chemical energy in our body (stored in the mitochondria due to the food we eat) which transforms into mechanical energy of the muscles.
Is the above correct?
If yes, how exactly does the chemical energy get converted into mechanical energy of the muscles?
In a game of billiards, energy is primarily converted from potential energy to kinetic energy. When the cue stick strikes the cue ball, it transfers kinetic energy to the ball, causing it to move. As the ball collides with other balls and the walls of the table, kinetic energy is transferred and converted into a combination of potential and kinetic energy.
Friction plays a crucial role in energy conversions in billiards. It helps slow down the movement of the balls, converting their kinetic energy into heat. This heat energy is then dissipated into the surrounding air, resulting in a gradual decrease in the overall energy of the system.
Yes, energy can be lost in a game of billiards. As mentioned previously, friction and air resistance cause a gradual decrease in the overall energy of the system. Additionally, some energy may also be lost in the form of sound as the balls collide with each other and the table.
The type of cloth on the billiards table can affect energy conversions in a few ways. A smoother cloth will result in less friction, meaning there will be less energy lost due to heat and sound. A rougher cloth, on the other hand, will result in more friction and a decrease in the overall energy of the system.
Yes, the angle of impact can affect the energy conversion process in billiards. When the cue ball strikes another ball at a more direct angle, more of its kinetic energy is transferred to that ball. However, if the angle of impact is more glancing, some of the kinetic energy may be converted into rotational energy instead of being transferred to the other ball. This can result in a different outcome for the movement of the balls on the table.
