Inertial to Gravitational Mass Ratio
According to Galileo's discovery the objects fall at the same rate due to the equality of inertial and gravitational masses. Where in our universe these two would not be equal? Following the question,...

An object falling from very far would have varying acceleration, how can that be accounted for?
I want to have a function that describes where a falling object is.
Like this one:
h(t) = -g*t²/2
But this one is for the usual close to the surface case, where there is no variation of gravity due to ...

What's the answer to this differential equation of a ball rolling in a semi-circle [closed]
Salute, everyone.
Let's assume a ball with a mass $m$ starts falling from the top of a frictionless semi-circular hole in the ground whose radius is $r$.
From Newtons second law, we have:
$$P_x = ma$$

Does Diamagnetism actually lessen G forces?
Example: Astronauts are pinned to their seats by 3gs during takeoff. If there were a sufficiently strong diamagnetic field, would the g-forces felt by the astronauts be lessened, or would they simply ...

If I hang from the ceiling of the elevator which is falling freely then will I experience weightlessness?
We all know that while the lift (or elevator) is accelerating downwards we feel less weight, now suppose I hang from the ceiling with the help of a stick in some cavity of the ceiling itself, then ...

What would happen if when falling down you get pushed up?
I know it will be a weird question, but im not a physics well informed person and I had this unsolved question for long time.
What would happen if lets say you are falling with someone else from ...

Maximum height reached by an object
Here, in the last line, from the formula s is negative, but how can s be negative?
Also, should it not be s=u^2/2g instead of
s= - u^2/2g?

Change in Path of a satellite on changing its velocity
When the speed of a Satellite travelling in a perfectly circular orbit is increased does the path of the satellite remain circular and the radius is increased OR does the path of the satellite follow ...

Why does the normal force go down in an downward accelerating elevator?
When standing in a stationary elevator the force due to gravity and the normal force cancel each other out hence the net force is 0. When the elevator starts accelerating downwards there's a net force ...

Separate the rotational acceleration from the gravity
I tried to plot the magnetometer and accelerometer readings: Fig1 and Fig2, respectively. The readings were collected by rotating the sensors around x,y,z axes. As you can see, the mag readings (Fig1) ...

What is the gravitational field in the middle of a thin rod?
I just calculated the gravitational field on the $x$-axis created by a thin rod of mass $M$ and length $L$ by applying the formula:
I got this:
However there are some issues that I don't get. If I ...

Forces to move a mass up and down and relation to potential energy [closed]
Basically the question is: Does it take the same forces to move a mass up or down including acceleration and deceleration?
The Newton second law: $F=m*a$ tend to say yes. In reality this is far from ...

Why acceleration due to gravity same for two objects of different masses (neglecting air resistance)? [duplicate]
If a feather ball and bowling ball are thrown , both reach the ground at the same time. (neglecting air resistance)
The reason given to this is that
Both the bodies have same acceleration .
My ...
