If the current flowing into and out of a 9 Volt battery is 1 Ampere, how much work is done by the battery in 10 seconds?

that potential difference has units of Volt and 1 Volt = 1 Joules/Coulomb.
A Volt represents the amount of work (in Joules) required required to move a charge through a potential difference.

What properties of a moving object are used in determining the object's energy of motion

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
