100

This is the energy an object has because of its position relative within a force field or because of the relative Positions of its components. 

What is Potential Energy?

100

This is the measurement of the rate of change with respect to time. 

What is speed?

100

This is the change in the direction of a wave as the wave moves from one medium into another. 

What is Refraction? 

100
This is the law that states all planets must travel around the sun in an elliptical pattern.

What is Kepler's 1st law?

200

This everyday object converts chemical energy into electrical energy.

What are Batteries?

200

This is the observation that when certain wavelengths of light strike a piece of metal, electrons are emitted, potentially creating an electric current. 

What is the Photoelectric Effect?

200

This piece of technology uses resonance to function. (MRI, Hologram, Endoscopy)

What is MRI?

200

This is the main idea behind Kepler's second law.

What is there is an equal area in equal time. OR ( The closer the object is to the sun the slower the orbit.) 

300

This is the equation for potential energy. (PE)

PE = mass * g * height

300

This is the equation for the velocity of a wave. 

v = f * λ 

300

This piece of technology uses diffraction to function. (MRI, Hologram, or Endoscopy)

What is Hologram?

300

This is the widest part of an ellipse.

What is the major axis?

300

The illustration shows the compression of a coiled spring caused by placing a 1-kilogram mass on it. Given the information in the illustration and understanding that the gravitational potential energy of an object on Earth can be calculated using the formula PE = m x g x h, in which m = mass in kilograms, g = the acceleration due to gravity, and h = height in meters, This is the change in mechanical potential energy of the spring after the mass was placed on it. 

What is an increase of 2.45 joules?

400

Joules are represented as (kg*m2*)/ s2. If we have a mass of an object at 1 kg, the acceleration due to gravity is 9.8 m/s2, and a height of 10m. This would be the potential energy in Joules.

What is 98 Joules? 

400

A cell phone is pinging a tower 400m away. The frequency of the wave is set at 10 hz and the wavelength is measured at 7m. This is the velocity of the wave.

What is 70 m/s? 

400

A wave has a velocity of 400 m/s. The frequency of this wave is 5hz. This is the wavelength of this wave. 

What is 80m? 

400

This is the point closest to the Sun in the orbit of a celestial body. 

What is a Perihelion?

500

This is the equation for kinetic energy

What is KE = 1/2 m*v2

500

In any given wave, when the frequency of the wave doubles (f = 2f),This will happen to the velocity.

What is the velocity will double (v = 2v)?

500

 Light approaches a solid opaque barrier with a slit in it. The Wave nature of the behavior of light would lead to the prediction that the light, on the other side of the barrier, would travel in this pattern. (Please illustrate the pattern)
