If you were to push a block in space in an ideal vacuum scenario with zero friction, what would be the final velocity of that object
2 votes

Yes, the time will matter. To calculate the final velocity of an object v ,with an inital velocity u,which is under a constant acceleration of a for a time t. We have the relation $$v=u+at$$ The ...

Consider Newton's law on inertia. He states that a body tends to remain in its state of rest or motion unless there was a net force on the body. Here the block has no net force acting on it since ...

Difference between Mass Number and atomic mass unit (AMU)
0 votes

The mass number is the number of nucleons as you said . The AMU is a unit that helps us to communicate weight of atoms in a better manner. eg) The mass of oxygen-16 atom is $2.65\times 10^{-26}$ kg. ...

Consider an impulse of J acting on blocks m1 and m3, the impulse does not act on m2 because there is no friction between any surfaces nor is there any other direct contact force. Hence by Applying ...
