Someone tells you that the velocity of a car is 55mi/h. Is this correct? Explain your answer

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy

At the negative terminal of the battery the electron has electric potential energy. what happens to this energy as the electron jumps from the negative to the positive terminal?
