Explanation:
kinetic energy is energy that it possesses due to its motion.
Answer:
The potential energy of the ball is 784 joules. And the kinetic energy of it is 392 while falling halfway down.
Explanation:
PE = mass (2kg) * Gravitational acceleration (9.8 m/s^2)* height (40 meters)
KE = 1/2 mass (1 kg) * velocity^2 (19.8)
If you mean in mass, then the mass of one proton is approximately equal to the mass on one neutron. If you mean how many of each, then the number of protons is equal to the number of electrons. If the number of electrons was different from the number of protons, then you'd have an ion. An ion with a positive charge is a cation, and an ion with a negative charge is an anion.
