A fly moving 5 m/s will always have more kinetic energy than an airplane at rest?
What is true?
100
This is the potential energy of a box with a mass of 50 kg that is 5 m above the ground.
What is 2500 J?
100
This is how many cans you will bring Mr. Ulle for the beard a con.
What is "as many as it takes to win!"
200
This is the SI unit of power
What is the Watt
200
This is the equation to calculate gravitational potential energy.
What is PE=m*g*h
200
A rock that is dropped and undergoes free-fall will strike the ground with exactly as much kinetic energy as it had as potential energy be fore it was dropped.
What is true
200
This is the potential energy of a 25N box lifted 4 m above the ground.
What is 100 J?
200
This is the teacher with the best beard
Who is Mr. Ulle
300
This unit is the equivalent to a kg * m^2/s^2
What is a Joule?
300
This is the equation to calculate kinetic energy
What is KE=1/2 * m * v^2
300
A ball that is thrown up has maximum potential energy when it hits the ground.
What is false.
300
This is the kinetic energy of 50 kg man running 10 m/s.
What is 2500 J.
300
This is how many cans you will bring Mr. Ull for the beard a con.
What is "as many as it takes to win"
400
This is the 1 MW expressed in SI units.
What is 10^6 Watts? (1,000,000 W)
400
This is the equation to calculate power.
What is p=w/t
400
If a lever is used to lift a 5 kg box, and the lever has a mechanical advantage of 2, then only 2.5 N of force is needed to lift the box.
What is false. (weight of box is 5*9.81 or about 50 N, it would take 25 N to lift the box)
400
This is the velocity before impact with the ground of a 1 million pound ball that is dropped from a height of 5 m.
What is 10 m/s?
v=sqrt(2gh)=sqrt(2*10*5)=sqrt(100)=10 m/s
400
True or false: If Mr. Ulle is winning the beard a con at the end of this week, all of his classes will get a Thanksgiving FEAST on Tuesday next week.
What is TRUE!!!
500
This unit is equivalent to a J/s.
What is a Watt?
500
This is the equation that relates the velocity of a dropped object, the moment before it hits the ground, to the height from which it was dropped.
What is v=sqrt(2*g*h)
500
If a lever has a mechanical advantage of 3, the input force would need to be applied for 3 times the distance that the output force is applied.
What is true.
500
This is 1 GW expressed in mW
What is 1x10^12 mW.
500
True or False, we will have a Feast next Tuesday because we will bring Mr. Ulle as many cans as it takes for him to be in the lead on Friday.
