What is the notation for the angular distance traveled by an object moving in circular motion?
s is for regular distance (m,ft,inches, etc.).
What I want is some x to be the distance in either degrees or radians.
How should I call that x?
As seen in the image below, a hand is pulling one end of a rope that is on a simple pulley, and the object W is pulling another end.
What I don't understand is what kind of force acts both objects P and W upward. The downward force is the force of gravity. Since I've learned that these kind of...
I understood this question right after putting it on this forum and I erased everything in the post (before anyone posted anything) because there is no 'delete post' button on this forum, but for some reason mods decided to recover the post... just ignore this post...
"It is not."
I understand that they're different. But they're not that much different - both are not negligible and not huge. When you jump, you use your mass + a bit more. When you fall, you use your mass + a bit more.
If I jump, I accelerate away from Earth.
However, if I drop a human on the ground, he doesn't accelerate away from the Earth.
In both cases the force used on the Earth is about the same, but acceleration away from the Earth exists in one case and doesn't exist in another case. Why so?
(not a...
The harder I push a book to a wall, the larger is the friction force, since friction is (coefficient of friction (times) the force I use).
Why won't the friction force make the object go up instead of stay where it is since the friction worse can get arbitrarily large while gravitational force...
