B Can Velocity and Mass Alone Create Force?

[John Clement Husain]

can we get Force with velocity and mass only?

Force of what, where, in which setup? Mass and velocity of what?

Your question is way too vague to answer.

Is this a homework problem?

 

[John Clement Husain]

No it isn't. Like the force of a punch or a rocket

 

[mfb]

Not without context.

A rocket at a given mass and velocity can either use its thrusters or not use them. The resulting force will be very different.

I think you mean impact force? An object in motion does not just "have force".

And the answer is still no: force for an impact(collision) is determined by the rate of deceleration, which depends also on the structure of the objects colliding. It doesn't have a single value and the variation throughout the impact can be very complex.

Do you mean formula $F=\frac{dp}{dt}=m\cdot\frac{dv}{dt}$?

It takes force to change the velocity of a mass.
