Jun 22, 2020 · "Net force" simply means the sum of all forces. The "unless acted upon by a net force" version is more correct. For example, as you stand or sit still, the earth pushes you up …

Oct 26, 2024 · 1 If the net force acting on the massless string was non-zero, mathematically that would mean the acceleration of the string is undefined, i.e., it could have any value. And yet, …

Mar 26, 2024 · According to Newton's Laws of Motion, if the net force is zero, then the object does not change its linear motion or its direction thereof. A non-zero net torque but zero force is fully …

Mar 16, 2024 · However, the solution manual say that the net force should be calculated by using the Pythogorean theorem. I believe am missing something as I don't really get why we need to …

Nov 15, 2021 · Why is the force that we feel the normal force, and not the net force? This is part of the key insight that led to the development of general relativity (GR). Einstein called it his …

Mar 25, 2022 · In classical mechanics, for this case, we say that the net force – the force of air resistance minus the force of weight – is zero, because the parachuter is descending at …

Sep 21, 2015 · There is an average force over a given period of time, and there is a net force on an object in an instant. What you're describing is really just an average forces, which you …

Jul 21, 2019 · Given no net force on an object, that object's inertia preserves its current state of motion, per Newton's 1st law. Once an object is moving at constant velocity, it DOES NOT …

Apr 4, 2019 · 1 I recently came across this diagram in my physics textbook I got a bit confused by this diagram. I thought that the reason why the object accelerates towards the center is …

Sep 16, 2021 · If we find the force for a decelerating object (let's say a car on a road), we'll see that the force is negative as in it’s in the opposite direction of the motion of the object. I wanna …
