How does Newton's Third Law apply to non-contact forces?
Feb 24, 2022 · 0 I always intuitively understood how Newton's Third Law applies to simple contact forces because I could imagine how to reciprocate the force of one object on another, the recipient's …
Normal Contact Force - Physics Stack Exchange
Dec 22, 2023 · The normal contact force is the force exerted by the wall on the rod that prevents the rod penetrating the wall. If the rod is free to move around on the wall (i.e. its end is not fixed in place) …
What is the difference between normal and contact forces?
Nov 29, 2021 · A contact force is any force that objects exert on one another because they make physical contact. But only the component of the contact force that is perpendicular to the surface is a …
Why is electromagnetism considered a non-contact force?
Sep 14, 2021 · The four fundamental forces (gravity, the strong force, the weak force, and electromagnetism) are all supposed to be non-contact forces. Yet, electromagnetism governs all …
Do contact forces form a field/wave? - Physics Stack Exchange
Feb 22, 2024 · Non-contact forces like gravitational forces exist between two objects in any medium because of the establishment of a field/wave. Since at an atomic level, 'physical' contact won't really …
Contact force betweeen 2 objects - Physics Stack Exchange
Jan 30, 2013 · 2 Suppose that we have 2 objects next to each other.The object at the left is A and the object at right is B.now we have these situations: 1) we push B to the left. 2) we pull A to the left. (in …
Why is gravity considered a non contact force? - Answers
May 26, 2024 · Non-Contact Forces While the ball is in the air, one force acting on it is gravity. Gravity pulls the ball down to the earth without touching it. This means it is an example of a non-contact force ...
Is the electromagnetic force responsible for contact forces?
Of the four forces, the only one that seems relevant is the electromagnetic force, and I always assumed the repelling force in question is ultimately the EM one. The Wikipedia article on contact forces …
forces - Can an object move without physical contact? - Physics Stack ...
Nov 29, 2017 · An object can move uniformly in a line by inertia without any force being applied, forces are needed only for acceleration. If you consider force fields to be "objects" then all forces come from …
Why are there so many fundamental differences between contact …
Feb 16, 2022 · Contact forces on the other hand act layer by layer from the contact surface on through the body being properly accelerated. But contact forces are in ultimate analysis are just …
