If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy is 15J.
If the kinetic energy of the ball decreases, then the potential energy will Increase.
The potential energy of the ball is 15 J.
Also if the kinetic energy of the ball increases then its potential energy decreases and the total energy will remain constant.
How do you calculate the potential energy?
Given that the total energy of the ball is 20 J and its kinetic energy is 5 J.
The total energy (TE) of the object is the sum of its kinetic energy (KE) and potential energy (PE).
[tex]TE = KE + PE[/tex]
[tex]20 = 5 + PE[/tex]
[tex]PE = 15 \;\rm J[/tex]
If the kinetic energy of the ball increases then its potential energy decreases and the total energy will remain constant.
If the potential energy of the ball increases then its kinetic energy decreases and the total energy remains constant.
Hence we can conclude that the potential energy of the ball is 15 J. Also if the kinetic energy of the ball increases then its potential energy decreases and the total energy will remain constant.
