Answer:
A) increase
2) decreases
3) increase
Explanation:
THIS IS THE COMPLETE QUESTION BELOW;
2.State whether the potential energy of the underlined object increases or decreases as a result of the change
1)A personclimbs a flight of stairs.
2)A diverdives into a pool
3)A hot air balloonlands in a field.
Kinetic energy can be regarded as a form of energy which an object posses as a result of motion. It can be regarded as energy that is associated associated with motion.
Kinectic Energy can be calculated using below formula.
K.E= 1/2mv^2
Where m= mass of the object
v= velocity of the object
It should be noted that Kinetic energy of a body depends on the velocity of the body squared. Whenever velocity of a body is doubled, then the kinetic energy of the body will quadruples.
1)A person climbs a flight of stairs.
As the person is climbing up, then he's doing that as a result of increase in his velocity and as the velocity increase, the Kinectic energy increases as he climb up the stair.
2)A diver dives into a pool.
As the driver drives into the pool , his Kinectic energy decrease, because his velocity will reduce as he enter the pool
3)A hot air balloonlands in a field.
The Kinectic energy will increase, because as a result of increase in velocity of the balloon
