list two ways to measure the gravitational potential energy of a ball when it’s dropped from different heights. Think about the motion of the ball and your energy flow diagram. Give an argument to support your choices. You can include methods that would not work with the simulation.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
