What are the two types of energy in projectile motion?
Kinetic, (1/2 mv2), and GPE (U = mg∆h)
During the ascent of a projectile the Kinetic energy ______ and the GPE ______.
Decreases, increases
During the descent of a projectile the Kinetic energy ______ and the GPE ______.
Increases, decreases
During projectile motion energy changes with (horizontal/vertical) displacement
Vertical —> same veritical displacement = same energy
