Suppose there's a block of some mass that is kept on a table. But, instead of staying at rest on the table, it breaks through the table. How does Newton's third law hold up here? If the block is at rest on the table then the push of the block onto the table due to its weight and the normal force ...

So I saw this article stating that gravity is stronger on the top on the mountain due to there being more mass under you however I have read some questions other people have asked and most of the responses state that the mass is concentrated at the middle of the earth meaning gravity doesn't get ...

From my understanding in space-time everything moves at the speed of light $c$ in some direction of this four dimensional space. Light itself moves only through space, so it doesn't move at all in time. So if a photon is 'created' in the sun (I have no idea how that works and if it even makes sen...

Let us consider this picture. $\Rightarrow$ The first picture shows the initial position of the block when the spring is in its natural length and is kept on a smooth horizontal table. $\Rightarrow$ The second figure corresponds to the situation in which the block is pulled straight on the smoot...
