Answer 2

When we throw a ball into the air it falls back  because of the gravitational pull that forces the ball back to the ground.

.The gravitational acceleration that act on the free falling object is the effect caused by the gravitational force.

•All the object left freely in the air has a tendency to to fall right back towards the earth.

•The ball does not posses enough kinetic energy to reach escape velocity from the current hight, and cannot stay still in the air therefore due to the gravitational pull it drops back.

.The respiration rate increases after work out is because our body uses more oxygen and produces more carbon dioxide.
