Two variables that measure how fast an object is going.
What are velocity and speed.
The concept that objects in motion stay in motion unless acted upon by an external force
What is inertia?
What is transferred?
The units for electric current
These waves move perpendicular to the wave direction
What are transverse waves?
The difference between displacement and distance
What is direction?
What is 50N?
A ball falls off a building. It has 100J of potential energy at the top of the fall. How much Kinetic Energy does it have at the bottom?
These are required for an electric circuit to function
This type of wave can travel in a vacuum
What are EM waves/Light waves?
A description of the velocity of these two objects
A: Initially stopped, but speeding up in the positive direction
B: Initially stopped, but speeding up in the negative direction
What is 50 Newtons? (Newton's 3rd law!)
An explanation of each of the three types of heat transfer while baking cookies in the oven.
What is conduction/convection/radiation and their answers?
These charged objects are said to attract, while this other is said to repeL?
Like charges repel, opposites attract
This wave travels faster in solids than liquids
What is sound
What is 5 seconds?
The way to survive an impact if you are falling out of a building is to increase what about the impact?
what is the time of the impact
This property of water makes it so difficult to heat up
What is its specific heat?
The total current flowing through a circuit with a 9V battery and 3 resistors with 0.5 Ohm's each?
What is 6A?
The property of waves when the bend THROUGH materials is called ____________
The property of waves when the bounce OFF materials is called __________
The property of waves when they spread out after passing through or around a barrier is called _________
(100 pt each, 100 for all 3)
Refraction
Reflection
Diffraction
What is 500 meters?
A 5 kg ball travelling at 2 m/s to the right hits a 10 kg ball that is stationary. The 10 kg ball then moves, but the 5kg ball stops.
The velocity of the 10kg ball is:
What is 1 m/s to the right
A 1 kg box is held 10m above the ground. Once dropped, it converts all the energy to electricity, but only gets 50 J of electricity out of the experiment.
The efficiency of this experiment is:
What is 50%
Two charged objects are 5 meters apart. They are moved to be 1 meter apart. The Force of electric charge is changed to be:
What is 25x stronger?
This type of nuclear radiation emits Helium in a fission reaction
What is Alpha?
