If you changed the surface of the incline the car is rolling down, how might that impact the distance and speed the car travels? Explain your answer using Newton's Laws.

Explanation: As the angle is increased the acceleration of the object is increased as the angle increases the component of the force parallel to the incline increases and the component of forced perpendicular to the inclined decreases it is the parallel component of the weight vector that causes the acceleration.

the bal will not change its velocity.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
