A few silly questions

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?
Can acceleration take place without time?
Is there such a thing as instant acceleration?
Can momentum change without time?
Can anything change without time?
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.
