What is Newton's 2nd Law of Motion?

Back

Force equals mass times acceleration (F = ma). It explains how the velocity of an object changes when it is subjected to an external force.

What type of wave requires a medium to travel?

Back

Longitudinal waves require a medium to travel and they move faster in warmer temperatures than in cold temperatures.

Front

What is nuclear fission?

Back

Nuclear fission is the process of dividing a large atom into smaller atoms, resulting in the release of energy and the production of radioactive materials.

What is mass?

Back

Mass is the amount of matter in an object, typically measured in grams or kilograms.

Front

What is electrical energy?

Back

Electrical energy is the flow of electrons, which can be used to power devices and perform work.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a large atomic nucleus into smaller parts, while fusion is the combining of two small atomic nuclei to form a larger nucleus.

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
