Physics
What is a force?
This is what speed measures.
What is the change in distance over time?
Mechanical waves require this to travel through.
What is a medium or matter?
This force is related to distance and mass.
What is gravity?
This person layed out 3 universal laws realted to motion and physics.
Who is Newton?
This law states that an object in motion stays at motion unless otherwise acted upon by an outside force.
What is direction?
This electromagnetic wave has the longest wavelength and is used to transmit information over long distances.
What are radio waves?
This type of magnet uses electricity to turn nonmagnetic object into magnets that can be turned on and off.
What is an electromagnet?
Something traveling at a speed of 2 miles per hour can travel this far in 5 hours
This is equal to Mass times Acceleration, according to Newtons second law.
What is force?
What is 5 miles per hour.
Electromagnetic waves are able to travel through this, which has no matter.
What is a vacuum, or space.
What are poles?
This force opposed forward motion and increases with rougher surfaces
What is friction?
If force is equal to mass times acceleration, how much force would it take to accelerate a 10 kilogram box 3 meters/s^2?
30 Newtons
If an object has a negative acceleration, this is happening.
It is slowing down.
As the frequency of an electromagnetic wave increase, energy increases, but this decreases.
What is wavelength?
Electricity is caused by the flow of this sub-atomic particle that is involved in chemical bonding.
What are electrons?
This force is directly opposite of gravitational force pushing down.
A rocket expelling gas downward, which pushes it upwards with the same amount of force, is an example of which of newtons laws?
Acceleration is a change in this over time.
What is velocity?
What is perpendicular?
What force keeps the moon from getting sucked into the earth?
Centrifugal Force
This color light has the most energy due to it having the shortest wavelenth
