Can You Pass Your High School Physics Class?

There are four laws of thermodynamics which are the first, second and third law of thermodynamics as well as the zeroth law. Each of the laws are important to remember as they affect physics as a whole.

Longitudinal waves are the type of waves that sound can travel through. These waves can travel through gases and liquids, but did you know that they can even pass through solids?

This one might have tricked you! This is the same equation as s=d/t, as velocity is another word that can be used for speed. Both will give the proper value, however.

This is true. Light is much faster than sound. You can test this by watching the sky during a storm. The lightning will show up before you hear the thunder!

Galileo conducted this famous experiment at the Leaning Tower of Pisa. It involved dropping two objects of different weights from the top to judge the velocity, and set the foundation for the physics that we learn today.

"Philosophiae Naturalis Principia Mathematica" was a book that Newton wrote in the 1600s which held all of the famous laws that he was known for. The book is important to modern physics, as they helped to advance the scientific thinking behind it.

Neils Bohr was a prominent physicist who not only worked in physics, but also chemistry. While you may know him from the Bohr model, he was actually an important figure in quantum physics as well.

If you take mass and divide it by volume, it gives you the density of an object. This is one of the more simple formulas in the subject!

This is true. Max Planck was a skilled physicist who laid out some of the foundation for modern physics. Quantum theory is just one of the ways he innovated the subject, and he was also the recipient of a Nobel Prize.

Acceleration is determined through both velocity and time. By using the proper equation, the answer is given to you in the format of meters per second. Now you can apply it to your car!

Force alters the movement of an object. For example, applying force on the opposite side of an object that is moving in a certain direction will cause it to move the other way. That is, if there is enough force applied.

Torque creates a rotation on an object. In order to calculate torque, you would use the formula t=r x F which takes the rotation and multiplies it by force.

The center of mass is most commonly located on the main body of an object. Knowing the center of mass of an object is important, as it can help determine things like movement and momentum.

This is true. Math is a large component of physics, as there are countless equations to know and use. It's important to understand how to use them as well as when to use them.

Inertia is a term that can be used for resistance. Did you know that it is important to Newton's second law of motion? It can also be a factor in a change in velocity.

V=IR is an equation that is part of Ohm's Law. The "V" stands for voltage, which is determined by multiplying current by resistance.

Joule heating is the term used for this concept. Joule is also a term used for the measurement of energy similar to the ohm. There are also many variants of the joule in different sizes like the zettajoule.

An ampere is a unit of electricity, but you probably know it better as the "amp". This the most common unit to be used when talking in terms of electricity.

This is true. Astrophysics is all about how elements in space work and move around. This field is large and filled with everything from quantum mechanics to thermodynamics.

Elementary particles are quite unique as they are not actually made of other particles. These particles typically make up matter and can combine together to form larger particles.

The correct formula for Hooke's Law is F=k x e. The formula relates to elasticity and force, and did you know that "k" relates to how stretchy a spring is?

Polarization affects the distribution of light. It can change all aspects of the light including what direction it is shining in. Think of the term when you wear polarized sunglasses!

This is the third law in Newton's three laws of motion. The three laws apply to the universe and help to explain how it all moves together.

This is true. The formula uses distance and divides it by the time in order to determine the speed that an object was or is traveling. This can apply to almost anything that's moving!

According to this law, they'll attract other particles to themselves. The theory was published in Newton's famous book, "Philosophiae Naturalis Principia Mathematica".

The Pythagorean theorem can also be applied to physics as it can be used to calculate angles. This can help to predict trajectory or slopes that can then be used to figure out other factors such as force or velocity.

An inductor stores this energy in a magnetic field. Inductors are also used to moderate currents going through them such as alternating currents.

A transistor can affect electronic signals. There are many different types of transistors that have all sorts of purposes.

This is false. The formula for work is actually measured in joules. It uses mass and multiplies it by the gravity in order to get the value of work.

Another word for density is mass. The density of an object can be determined by the mass and volume divided by each other.

General relativity and special relativity are the two concepts that make up the Theory of Relativity. This theory originated from Albert Einstein, and it is most commonly related to space matters.

As geodesic is used in terms of curves, a sphere would be one of the shapes it could be used for. It is used to refer to the smallest space between points on a curve.

This is false. We're talking physics here! This equation will actually find the pressure of an object by dividing the force and area by each other.

Isotopes are elements that are the same, but differ in their masses. This is because one will typically have more neutrons than the other, creating more weight.
