what action on our part is neccesary to make the dryiceblock move faster and faster,that is accelerate continuosly?if you are speeding it up, how must you move?
To accelerate at a constant rate you need to apply a constant force. The larger the force, or the lower the friction coefficient, the faster the acceleration.
I have no idea what kind of an experiment you are referring to. Were you supposed to have conducted a lab experiment?
