Describe the path of the electric current through a circuit?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
