Periodic Table/Conserving Energy

Front

What is the atomic number on the periodic table?

Back

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

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

How does increasing speed affect kinetic energy?

Back

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

Front

What happens when two skaters push against each other?

Back

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

Front

What is the difference between atomic mass and atomic number?

Back

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

Front

What is the formula for kinetic energy?

Back

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

Front

What is the law of conservation of energy?

Back

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

Front

What is an example of potential energy?

Back

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

Front

What is an example of kinetic energy?

Back

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