Which statement is true about a falling object? (Assume no air resistance)
1. The kinetic energy of the object is conserved.

2.The difference between the kinetic and potential energy of the
object remains the same.

3.The potential energy of the object is conserved.

4.The sum of the kinetic and potential energy of the object remains
the same.

I would say the answer is 3 because by falling technically the ball would be kind of moving in the air. Plus potential energy is when for example a soccer ball isnt moving

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

the answer is b
