Explanation:

- Acceleration: All objects, regardless of mass, fall with the same acceleration due to gravity (ignoring air resistance). This is why both the iron and aluminum spheres have the same acceleration when they are 10 meters from the ground.

- Kinetic Energy: Kinetic energy depends on both mass and velocity. Because the spheres have different masses, their kinetic energies will not be the same.

- Momentum: Momentum is the product of mass and velocity. Since the spheres have different masses, their momenta will be different.

- Potential Energy: Potential energy depends on mass, gravity, and height. With different masses, the potential energy of each sphere differs.
