Potential energy:
Kinetic energy:
For aluminum:
energy is conserved during the fall and that 100% of the sphere’s initial potential energy is converted to kinetic energy
Consider the two spheres shown here , one made of silver and the other of aluminum. The spheres are dropped from a height of 2.1 m.
What is the velocity of the aluminum sphere at the moment it hits the ground? (Assume that energy is conserved during the fall and that 100% of the sphere’s initial potential energy is converted to kinetic energy by the time impact occurs.)
