# 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 discussion of energy, momentum conservation etc., use classical-mechanics, for Newton’s description of gravity, use newtonian-gravity.

### Minimum calculus for Lagrangian Mechanics [on hold]

I have noticed in my classical mechanical books, the development of the motions of equation for simple systems using the Lagrangian that the main complication, if doing the work by hand, is applying ...

### How does the math of storing energy in a spring work in a moving frame?

Consider a spring with spring constant $k$ attached at one end to a wall. When an external force stretches it by distance $l$ in the positive direction the force does work $\frac{1}{2}kl^2$ and that ...

### Experiment in dynamics/newton's laws

During my physics class the teacher demonstrated an experiment to us: The teacher said that if we pull the rope slowly than the rope will tear at connection A, but if we pull the rope instantly/with ...

### When I pull a rope attached to a block, does the rope OR the block pull me back? If so, with what force?

I am having a hard time understanding the tension force, especially when thinking about it at a molecular level. Suppose I have a rope attached to a block which is sitting on frictionless surface. ...

### Kinematics problem, only energy related approach [on hold]

I read this question: From the top of a tower, a stone is thrown up and it reaches the ground in time $t_1$. A second stone is thrown down with same speed and it reaches the ground in time $t_2$. A ...

### The origin of normal reaction

I want to know what actually is the origin of normal reaction between 2 objects. i have read about normal reaction from several books which generally mention it as a component of contact force which ...

### Distance between two drops

2 drops are thrown away simultaneously in $t=0$, with initial velocity of $v_i$ and in angle of $\theta_i$ in opposite directions as seen in the picture. What is the distance between them as a ...

### Motion of a car on a banked road

I have read about the motion of a car on a banked road. I read that the maximum possible speed of a car on a banked road is greater than that on a flat road. I know the formula for finding velocity ...

### Difference between the Coriolis effect and the Eötvös effect

The coriolis accelaration is $-2\Omega \times u$, where $\Omega$ is the earths rotation and u is the velocity in a basis following the earth. When something moves east/west, this results in ...
