When a ball drops from the roof of a building, it speeds up as it falls. what energy transformation is happening?

a. gravitational potential energy to kinetic energy
b. kinetic energy to gravitational potential energy
c. light energy to sound energy
d. gravitational potential energy to nuclear energy

As initial position of the ball is upwards and at some height above the surface of Earth

so here we can say that initial total energy of the ball is in the form of gravitational potential energy

this is given by equation

here we know that

h = initial height of the ball from ground

now again we know that ball is released from rest from that initial height and it continue from this position

As it start falling down the speed of the ball will increase due to gravity so here we can say that as ball go down its kinetic energy will increase

so here correct answer for energy transform is

A. Gravitational potential energy to kinetic energy

The answer is A. Gravitational potential energy to kinetic energy

First, the ball is experimenting gravitational potential energy since it hasn´t been dropped.

Then, the gravitational energy turns into kinetic energy. The ball gains speed because of the acting of the gravity acceleration which is equal to . But, what does it that means? It means that every second while the ball is falling, its velocity will increase at a speed rate of

The gravitational potential energy is equal to:

Where

The kinetic energy is equal to

Where:

Have a nice day!

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

yup its correct its: c) b b
