The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp. A. The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.

B. The gravitational potential energy decreases and the kinetic energy increases. As soon as the ball starts moving it no longer has gravitational potential energy; it has only kinetic energy.

C. The kinetic energy and and gravitational potential energy both decrease. Both forms of energy are used up as the ball moves and are not transformed into any other form of energy.

D. The gravitational potential energy and the kinetic energy both stay the same. One form of energy cannot be transformed into a different form of energy.

The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.

Explanation:

The gravitational potential energy is the energy due to the position of a body above the ground.

Kinetic energy is the energy due to the motion of a body.

From the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".

As the ball rolls down the ramp, the potential energy at the height is converted to kinetic energy.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
