A capital "T" in an equation stands for period. This representation works hand in hand with frequency, and refers to the time it takes something to complete an action.

a=F/m is the correct equation. It reverses and uses division of force from mass to get the acceleration. Now that you know these two equations, tell us how to get mass!

A capital "K" in an equation represents kinetic energy. Kinetic energy is accumulated by an object moving at a certain speed. Kinetic energy, however, can be converted into other types of energy as well.

The correct equation for the area of a rectangle is: A=bh. In this equation, a is area, b is base, h is height. Filling in the base and the height, then multiplying will give you the area of the rectangular object.

This is true. Laplace's Law is used for electromagnetism, pressure measurements and many more. It even has a place in healthcare, as it can gauge pressure.

The time of flight formula is used for this. It takes the velocity and multiplies it by the sin of the angle the projectile was launched, then divides it by acceleration.

The formula for magnetic force is F=qvB. This equation can also be used in regards to a negative charge by placing a negative sign (-) in front of qvB.

Albert Einstein developed the theory of relativity, which is still a main part of all physics today. With the development of the theory came many previously unknown concepts that could suddenly be calculated and used to our advantage.

The Ancient Greeks were the first to base their physics on mathematical equations and proper science. Their contributions only helped to kickstart the useful knowledge that we have on the subject today.

This is true. The Fb in the equation stands for buoyancy force, while the pgV is density, gravity and volume. Multiplying all three together solves for the buoyancy force.

The rotation curve of a galaxy measures the speeds of stars. This typically refers to and is used when in relation to a spiral galaxy.

The capital "V" in an equation stands for volume, and we're not talking about turning up your music! Volume in this case refers to the inside of a solid object.

Kelvin is a unit of measurement that is used in regards to temperature. The unit was named after its founder, Lord Kelvin, who also studied the concept of absolute zero.

Molar mass is measured in moles, as well as kilograms. No, not the animals in the ground! Mole is part of the International System of Units and has been the subject of debate a few times.

This is true. There are a number of different equations that can calculate many aspects of free falling. For example, distance and time equations are used in relation to each other and to gauge the fall.

The missing element is "m". In this equation, "F" means force, while the "m" and "a" means mass times acceleration. This is used to calculate the force needed to help an object of a certain mass to accelerate.

A lower case "x" stands for position within an equation. A lower case "y" can also indicate this, as the corresponding letters refer to the x and y axis on a chart.

This equation is one of the most famous in the world, and was developed by Einstein. The equation is used to calculate energy through mass and the speed of light. His development was first made public back in 1905!

A joule is a unit of measurement that measures energy. Did you know that there are many types of joules? They include a millijoule, a nanojoule and a kilojoule.

This is true. The impulse equation multiplies force by time to get the value of impulse. Did you know that impulse is typically measured in newtons?

Drag is a type of friction, and when it takes place, it causes resistance in some way. Drag can be calculated through a number of different equations.

A triangle symbol is a Greek symbol that stands for delta. This is used when there is a change taking place within the equation. It is most commonly placed alongside a letter that gives it more meaning as to what is changing.

Ampere's Law is a complicated equation that is used to measure magnetic fields. It also has to do with conducting electricity that then produces a magnetic field.

The correct formula used to calculate density is mass over volume. This means that you divide the mass of an object by its volume in order to get the answer of its density.

This is false. The correct equation for flow rate is Q=Av. The way it is calculated is by taking the area and multiplying it by the speed to get the flow rate.

An ohm is a unit of resistance that is used to measure electricity. You may have also heard of Ohm's Law, which is all about the consistency of a current through a conductor.

By subtracting 273.15 from the Kelvin temperature, you get the same temperature in Celcius. This is because, that is the difference between the two temperatures when neutral.

Absolute zero is a temperature of -273.15 Celcius. The temperature is said to be the lowest possible temperature, which can also affect the motion of the object that is subject to it.

This formula is used to calculate weight based on mass multiplied by gravity. Did you know that gravity is a factor when determining how much you weigh?

This is false. This is actually the equation to solve for the value of an electric current. You may even know it better as Ohm's Law, taking voltage and dividing it by resistance.

As the EOT at the beginning of the equation states, this equation is used to calculate time. The difference of this equation is that it works in relation to solar time.

The symbol "p" is used to represent the value of pica. Did you know that the value of pica is 0.000,000,000,001? It's pretty small, just like its symbol!

The Doppler Effect takes effect on sounds that we hear. It has to do with the sound waves that we hear and how close they are in relation to us.

This is true. The photoelectric formula is solved by adding the electron energy to the work force. This is turn gives the value of Planck's constant and frequency.

Max Planck's development of quantum physics changed the world, but so did his discovery of the energy quanta. You don't win a Nobel Prize for nothing! His incredible work is still used today.
