Questions tagged [newtonian-mechanics]

Newtonian mechanics covers the discussion of the movement of classical bodies under the influence of forces by making use of Newton’s three laws. For more general concepts, use [classical-mechanics]. For Newton’s description of gravity, use [newtonian-gravity].

Doppler effect with circular motion [closed]

I've been struggling with this question that turned up in a physics exam last year and just can seem to get anywhere close to the answer. From the attached picture: An object is moving in a circle ...

Variation of Intrinsic losses w.r.t spring constant

How intrinsic friction losses (or energy losses) of a real spring varies w.r.t its spring constant? I am not expecting a direct relationship between the two, but at least whether more stiffer springs ...

Mass calculation of a body having a constant horizontal force of 10 N which travels 18 m in 6 seconds? [closed]

How i must calculate mass of a body having a constant horizontal force of 10 N which travels 18 m in 6 seconds? I had thought of finding acceleration in order to apply the second law of dynamics, but ...

Pulley problem: I included the here the the picture of what i already tried doing [closed]

Pulley problem Problem: Find the tensions in the two cords and the acceleration of the blocks if friction is negligible. The pulleys are massless and frictionless, m1=200g, m2=500g and m3=400g. I am ...

When to use $x = A \sin (wt + p)$ and $x = A \cos (wt+p)$ during Simple Harmonic motion when we start our clock not between mean and extreme position? [duplicate]

When to use $x = A \sin (wt + p)$ and $x = A \cos (wt+p)$ during Simple Harmonic motion when we start our clock when the object is between mean position and extreme position ? I have been trying to ...

How to find angle using $Ļ = IĪ±$? [closed]

I want to find angle (radians) using the formula: $Ļ = IĪ±$ . I guess after finding angular acceleration Ī± I have to do an integration but I am not sure which method I should use.

Explain briefly why the total mechanical energy is not conserved

A uniform circular disk is free to rotate in a vertical plane about a smooth horizontal axis through its center $O$. An insect P is at the lowest point A of the disk and the whole system is at rest. ...

Newton 3rd law confusion [duplicate]

Why do things even move? I mean based on Newton 3rd law no matter how much force you exert on an object, it will always exert an equal and opposite force back to you. So why do things move?

Why does normal force work?

I've got a lot of question about normal force. First, what causes normal force. Next, how do the object know how much normal force to exert. Lastly, how is this not an application of Newton 3rd law. ...
