Hello folks,

I'm engaging in discussion with someone and have found myself going around
in circles, so I'd appreciate some help with a few mundane questions:

Can velocity change without time?

Velocity is defined as the derivative of position with respect to time.

Can acceleration take place without time?

Acceleration is *defined* as the derivative of position with respect
to time.

Is there such a thing as instant acceleration?

Acceleration at any point in time has a value.


Can momentum change without time?

Can anything change without time?
No


Is this statement true: "But when no distance is covered against or with the
force, no work is done
and energy is neither stored nor expended."?

Thanks for your time.
