Two students are practicing hitting baseballs off of a tee. The first student says the baseball has the same amount of inertia regardless of how hard you hit it, but it will accelerate twice as fast if you hit it with twice the force. The second student argues that it will accelerate twice as fast if you hit it with twice the force, but says the ball that is hit harder will have twice the inertia. Who is correct, and why? A. The first student is correct, because inertia describes an object’s resistance to change in motion with respect to its amount of mass only.

B. The second student is correct, because inertia describes an object’s resistance to change in motion with respect to its amount of mass and speed.

C. The first student is correct, because inertia describes the energy that an object contains when it is not moving.

D. The second student is correct, because inertia describes the energy that an object contains, and objects that are moving have more energy.
