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.
http://scienceworld.wolfram.com/physics/Acceleration.html

Is there such a thing as instant acceleration?

Acceleration at any point in time has a value.

Can momentum change without time?

Conservation of Momentum
http://scienceworld.wolfram.com/physics/ConservationofMomentum.html

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."?

Work

Thanks for the links. By the way, I'm not just asking these questions
because I'm too lazy to do any study, but that without any outside input, I
get the feeling that the person I'm arguing with feels at liberty to call
anything I say, wrong, regardless of its merits.
