For each drop, she calculates what the kinetic energy of the ball would be when it hits the ground. The table shows her data.
Height of Drop (meters) Kinetic Energy (joules)
1.0 48
1.5 72
2.0 96
Iesha says that a ball dropped from a height of 3.0 meters would have less than 96 joules of kinetic energy when it hits the ground. Is she correct and why?
A.
She is correct because the higher the ball is dropped from, the less kinetic energy it will have when it hits the ground.
B.
She is correct because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
C.
She is incorrect because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground.
D.
She is incorrect because the higher the ball is dropped from, the less kinetic energy it will have when it hits the ground.
D. She is incorrect because the higher the ball is dropped from, the greater kinetic energy it will have when it hits the ground. This is based on the relationship between potential energy (height of drop) and kinetic energy, where potential energy is converted into kinetic energy as the ball falls.
