Question

Consider an object launched vertically upward with an initial speed v. Neglect air resistance.

1. As the projectile goes upward, what energy changes take place?
   • Both kinetic and potential energy decrease.
   • Both kinetic and potential energy increase.
   • Kinetic energy decreases; potential energy increases.
   • Kinetic energy increases; potential energy decreases.
2. At the top point of the flight, what can be said about the projectile's kinetic and potential energy?
   • Both kinetic and potential energy are at their maximum values.
   • Both kinetic and potential energy are at their minimum values.
   • Kinetic energy is at a maximum; potential energy is at a minimum.
   • Kinetic energy is at a minimum; potential energy is at a maximum.
