Periodic Table/Conserving Energy

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Potential energy is stored energy that has the potential to do work, such as energy stored in an object due to its position.

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Increasing an object's speed will increase its kinetic energy.

Both skaters will roll backward at the same rate due to the conservation of momentum.

Atomic mass is the weighted average mass of an element's isotopes, while atomic number is the number of protons in the nucleus.

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

A rock held at the top of a hill has gravitational potential energy due to its height.

A moving car has kinetic energy due to its mass and speed.
