Question

If an object falls twice as far, how do you think the energy acquired changes? halves

doesn't change
doubles
quadruples

Answer 1

Doubles

Step-by-step explanation:

Before starting to fall, the object will have energy in the form of potential energy. This will be the energy that will be transformed into kinetic energy, once the object starts its fall. And the potential energy that the object had before starting to fall, will be equal to the kinetic energy acquired during the fall. The potential energy is given by:

`E_p = m*g*h`

Where m is the mass of the object, g is the gravity, and h is the distance to the floor. As you can see, The potential energy is proportional to the height of the fall, so if this height doubles, the potential energy and therefore, the kinetic energy acquired will doubles.
