Photon
A glass shape with flat, polished surfaces that can both bend and reflect light.
Prism
A cart is rolling down a ramp. If the angle of the ramp is increased to make the ramp steeper, the cart will...
increase its acceleration
What are the three "action at a distance" forces?
Gravity, Electricity, Magnetism
There are two springs. The first spring exerts a force of 10 N when stretched 10 cm, what is the force exerted by the second spring when stretched 5 cm?
5 Newtons
A wave where the oscillations travel in the opposite direction as the wave.
Transverse
A graph that shows the frequency, amplitude, and time length for a sound.
Sonogram
What is the speed of an object traveling 3 meters every 5 seconds?
.6 m/s
From an origin of (0,0) you travel 4m North, 3m West, 5m South, 4m East, and 2m North. What are the coordinates of your ending position?

There are two stacks of books. One has a mass of 5kg and the other 10 kg. How do their WEIGHTS compare?
The 10 kg stack of books would have twice the weight of the 5 kg stack.
Define Absorption of a wave.
What happens when the amplitude of a wave get smaller and smaller as it passes through a material.
The formula for frequency is…
1 divided by time (in seconds)
An apple tree is 3.5 meters tall at 6 years old and 4.5 meters tall at 8 years old. How tall would the tree be at 10 years old?
About 5.5 meters
A force vector is drawn 6 cm long and pointing to the left. If the scale of the force vector is 1 cm = 3N, what is the value of the force?
-18 Newtons
What are Newton's three laws of motion.
An object in motion stays in motion unless acted on by an unbalanced force.
Force equals mass times acceleration.
Every action has an equal and opposite reaction.
Define Resonance
An exceptionally large amplitude that develops when a periodic force is applied at the natural frequency.
Define Color
The sensation created by the different energies of light falling on your eye.
If a plane flies 400 km East and then 300 km South. The coordinates of its new position would be what?
(400 km, -300 km)

1 lb = .448 N
1 kg = 9.8 N
1 kg = 2.2 lb
A car drives along the highway at a constant velocity. Find the car’s weight if the engine produces a force of 2,000 N and the normal force on the car is 12,000 N.
12,000 N
Define Fluorescence
A process that makes light directly from electricity.
Define Index of refraction
A number that measures how much a material is able to bend light.
