What is the difference between a force and a net force?
Jun 22, 2020 · 5 "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 with a force …
How can a body have constant velocity when net force on it is zero?
Jun 22, 2019 · I am asking is that, if a body has a constant speed then net Force on the body is zero and force is directly associated with acceleration, so how a body even move with constant velocity.. Or …
Why does "net force" being zero not mean that the parachuter …
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 constant …
About constant velocity linear motion with zero net force
Aug 18, 2023 · When the expression zero net force is in the 1st law, the concept of net force actually comes from the 2nd law, which is implicitly assumed in the 1st law. If inertial motion is defined as …
How can a body even move if no net force is acting on it?
Jul 21, 2019 · A force would be required to start it moving, but no force is necessary to keep it moving. A body moving at constant velocity on a surface with friction where the force pushing the body exactly …
How is rotational motion possible when net force is zero?
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 allowed …
Average Force vs Net Force - Physics Stack Exchange
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 could obtain …
How does Newton's Third Law hold in cases of net force?
Mar 7, 2022 · In a case where there is a net force, how does Newton's Third Law hold? For example, if I give a book a push and it starts to slide across the table, that means it was not able to neutralize the …
Why is the centripetal net force always to the center?
Apr 4, 2019 · I thought that the reason why the object accelerates towards the center is because of a net force, not because of velocities being added together. So my question is: what forces do we use to …
Why do we use the Pythogorean theorem for the net Force in this …
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 do that, …
