Question
Which statement best describes the change in energy as an object is moving up toward the highest point of its motion during projectile motion?Multiple choice question.The kinetic energy is increasing while the gravitational potential energy is decreasing.Both the kinetic and gravitational potential energies are increasing.Both the kinetic and gravitational potential energies are decreasing.The kinetic energy is decreasing while the gravitational potential energy is increasing.
Solution
The correct answer is "The kinetic energy is decreasing while the gravitational potential energy is increasing."
Here's why:
-
Kinetic Energy: This is the energy of an object due to its motion. As an object moves upwards in projectile motion, it slows down due to the force of gravity. As speed is a component of kinetic energy, the kinetic energy decreases as the object slows down.
-
Gravitational Potential Energy: This is the energy an object possesses due to its position relative to other objects, in this case, the Earth. As the object moves higher, its distance from the Earth increases, which increases its gravitational potential energy.
So, as an object is moving up toward the highest point of its motion during projectile motion, its kinetic energy is decreasing (because it's slowing down) and its gravitational potential energy is increasing (because it's getting further from the Earth).
