A student wants to support the claim that in order to accelerate a heavy object and a light object the same amount, more force will be needed to accelerate the heavy object. Which investigation would best help the student support their claim? Apply the same amount of force to two citjects of the same mass and measure the distance they travel. Measure the amount of force needed to accelerate two objects of different mass on different types of surfaces. Measure the amount of acceleration that results from applying different forces to a very heavy object. Apply force to two objects of different mass until they reach the same acceleration; then measure the forces.
