Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its ---------------- energy increases and its ---------------------------- decreases.
Answer:
Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.
Explanation:
Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.

How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall.
Answer:
Because it is charged with the opposite type of energy to the wall.
Answer: A
Explanation: The positive charges of the uncharged wall move to the outside.
all light is the same whether it comes from the sun a light bulb or anywhere
do you agree with this statement explain
All light being the same whether it comes from the sun a light bulb or
anywhere is False.
What is Light energy?This is a type of kinetic energy which makes light to be visible to the eyes.
There are different sources of light which include:
SunElectric bulbCandle etc.Light from bulbs and Sun involve photons being emitted at different
intensities which is why the light from both sources are different. The
Sun has more intensity and a different source than the Light bulb.
