The kinetic energy of an object is directly proportional to its mass. Therefore, the marble with the greatest mass will have the greatest kinetic energy. In this case, the marble with the greatest mass is: D. 6 grams
In the investigation on energy, the kinetic energy of a rolling marble is directly influenced by its mass. According to the principles of kinetic energy, which is proportional to mass, the marble with the greatest mass will exhibit the highest kinetic energy.
Therefore, among the options provided, the 6-gram marble (Option D) is expected to have the greatest kinetic energy when it reaches the bottom of the ramp.
This relationship underscores the significance of mass in determining the energy associated with the motion of objects, emphasizing the fundamental principle that heavier objects possess more kinetic energy than their lighter counterparts.
The complete question is:
During an investigation on energy, Seth rolls marbles of four different masses down a ramp.
Which size marble will have the greatest kinetic energy when it reaches the bottom of the ramp?
A. 2 grams
B. 3 grams
C. 5 grams
D. 6 grams
