What is Change in momentum times time?

Impulse = [(change in momentum)/time]*time[(change in momentum)/time] = ForceAnd when force acts for a period of time, that impulse changes the momentum of the object.You can also rewrite the impulse equation as: I = F*tHowever, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m. These units are not in common usage.


What are the dimensions of the force f knowing that f is equal to the mass m times the acceleration a?

[ force ] = [ mass ] [ acceleration ] = [ mass ] [ length/time2 ] = [ mass-length-time-2 ]


What is the dimension of force if density and frequency and acceleration due to gravity are the bare quantities?

Frequency and density aren't involved as 'bare quantities' in force. The bare quantities that constitute force are mass, length, and time, and the physical dimension of force is (mass) x (length)/(time)2 . The 'length' and 'time' combine to result in (length)/(time)2, and that's the 'acceleration' that you did include.


What does force divided by distance equal?

Work is force times distance. A Force divided by Distance: looking at the units, Force = newtons = kg m / s^2 = mass x length / time^2 so ML/T^2 Distance = m = length so L Force/Distance = (ML/T^2)/L = ML/LT^2 = M/T^2 So the units of a force divided by distance are mass/ time^2 This would be the rate of change of mass change with respect to time.


The force of a gravitation between two objects is 500 newtonswhat would the force of gravitation be if the distance between these two objects increased by 10 times?

when the distence between the two objects is increased by ten times then the force of gravitation will reduce by 100 times.
