An object with a mass of 4 kg travels 15 meters in 3 seconds. What is the objects kinetic energy? ? ( Use V - to find the velocity)

How would doubling the made of an object change the objects potential energy

An object starts from rest at point f and speeds up continuously as it moves around an oval. a. choose a point about 1/8 th of the way around the oval from point f, and label it point g. draw a vector to represent the velocity of the object at point g. b. determine the change in velocity vector   between points f and g.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
