In this lab you will use a cart and a track to explore Newton's second law of motion. You will vary two
different variables and determine how each one affects
how quickly the cart moves along the track. In the space
below, write a scientific question that you can answer by
doing this experiment.

As newton's first law states a object in motion stays in motion

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
