Electricity&Magnetism
This type of circuit only has one path for the current to flow through.
What is a series circuit?
Waves travel fastest in this state of matter.
What is solids?
This law states that energy can neither be created nor destroyed, but only transferred or transformed.
What is the Law of Conservation of Energy?
Newton's first law is also called this.
What is Law of Inertia?
This is what waves transfer.
What is energy?
The magnetic field is strongest around this part of the magnet.
What are the poles?
This type of wave does not require a medium or matter to travel.
What is Electromagnetic Wave?
This type of energy is the stored energy in a battery.
What is chemical energy?
If two spheres with the same diameter but different composition fall freely from the top of a building and friction is ignored, the spheres will have the same _________.
What is acceleration?
If you traveled a distance of 90 km in 2.0 hours, this would be your average speed (make sure to include units).
What is 45 km/hr?
This is what happens to the other lights when one light goes out in a parallel circuit.
What is they stay on?
Objects that absorb all colors of light and reflect little or no light back to your eye will appear as this color.
What is black?
A solar cell converts this type of energy to electrical energy.
What is light (or radiant) energy?
This term refers to the force of gravity pulling on an object's mass.
What is weight?
This type of heat transfer is why a car is hot on a summer day.
What is radiation?
If a car radio has a resistance of 15 ohms and draws a current of 0.87 amps, then this is its voltage (must include units).
What is 13.05 volts?
Radars make use of this type of electromagnetic wave.
What are radio waves?
A student holds a ball out of a window in a tall building. The ball is 30.0 m above the ground and has a mass of 0.85 kg. This is the gravitational potential energy of the ball (must include unit).
What is 249.9 Joules?
This is what velocity has that speed does not.
What is direction?
If a 16,000 kg truck is moving at a speed of 25 m/s, this is its momentum (must include units).
What is 400,000 kgm/s
If a circuit has 150 volts applied and draws 0.3 amps of current, then this is its resistance (must include units).
What is 500 ohms?
This is what happens to the wavelength of a wave if its frequency doubled.
What is decreased by half?
If a 2.0 kg ball is moving at a speed of 4.0 m/s, then this is its kinetic energy (must include units).
What is 16 Joules?
A sudden gust of wind increases the velocity of a sailboat relative to the water surface from 3.0 m/s to 5.5 m/s over a period of 3.0 seconds. This is the average acceleration of the sailboat (make sure to include units).
What is 0.83 m/s2?
When looking at a Distance vs. Time graph, this is how you determine the speed over a certain period of time.
What is find the slope?
