  • A) Taylor Swift

  • B) Drake

  • C) The Weeknd

  • D) Ed Sheeran

C) The Weeknd

200

This type of energy is dependent on the mass and velocity of the object being analyzed

Kinetic Energy

200

You are hungry so you go and grab some bread to make toast. You put the bread in the toaster and turn it on. What two energy transformations are occurring between the electrical socket and the metal toaster grid.

Electrical -> Heat

Electrical -> Light

200

Power is calculated by dividing what two quantities?

Work and Time

200

True or False: Momentum is sometimes conserved in any given scenario

FALSE! It is always conserved

Question: Which of these animals is biologically considered "immortal" because its cells can revert to their earliest stage of life, allowing it to bypass death from old age? 

  • A) The Axolotl

  • B) The Greenland Shark

  • C) The Turritopsis dohrnii

  • D) The Tardigrade

C) The Turritopsis dohrnii

300

This type of energy is generated through waves that propagate through a medium and are processed in the brain as one of the five senses.

Sound Energy

300

Velocicoaster uses electromagnets to launch trains from 0 - 55 mph in seconds. Later in the ride, a second launch sends riders to the top of a 155 ft top hat element. Describe the energy transformation between the coaster and its surroundings from the second launch to the top hat.

Electrical -> Mechanical -> Gravitational Potential

Electrical -> Kinetic -> Gravitational Potential

300

2 trains are pulling against each other along a straight track. Train A eventually prevails in pulling train B; however train B continues to try and slow Train A down. Is train A doing positive, negative, or zero work?

Positive (Net Force is in the direction of Train A)

300

Sammy lifts a barbell doing 100J of work in 10s. How much power did Sammy output to lift the barbell? (Accurate Units are required for points)

10 Watts

While NASA celebrated eating "space salad" in 2015, which country grew the first plants in space (specifically onions and peas) in the 1970s?

  • A) USA

  • B) Soviet Union (USSR)

  • C) China

  • D) Japan

B) Soviet Union (USSR)

400

This type of energy is released when electrons change energy levels releasing photons.

Light/Radiant

400

A solar farm powers farm equipment used to harvest apples for human consumption. Describe the energy transfer from the perspective of the solar panels collecting the energy

Light/Radiant -> Electrical

400

A satellite is in orbit around the earth. The earth's gravity pulls the satellite inwards as the satellite moves in a circular path around it. What type of work is the earth doing on the satellite?

Zero The force of gravity is perpendicular to the circular motion of the satellite

400

A rollercoaster enters a loop with 25KJ of Kinetic Energy. When it leaves the loop, it only has 20KJ of Kinetic Energy. How can this be possible if the entrance and exit of the loop have the same height?

Energy was dissipated through sound and heat due to friction!

400

  • A) Switzerland

  • B) El Salvador

  • C) Japan

  • D) Brazil

B) El Salvador

500

This type of energy is associated with stored potential energy stored in an elastic material

Spring Potential Energy

500

This law states that energy cannot be created or destroyed.

The Law of Conservation of Energy

Jack and Jill are competing in a weightlifting competition. Jill lifts more weight than Jack, but Jack lifts his weights faster than Jill. If both competitors are lifting the weights to the same height, who is doing more work?

It depends! We don't have enough information to make a conclusion.

You'll see an example of this a little later!

500
After beating Jack in the weightlifting contest, Jill buys a new handbag to celebrate, as she is walking back home with her new bag, it catches on the door handle. She maintains her balance with ease, but the sudden change in momentum causes the bag to fall 3 feet to the ground. In this example, what kind of work does gravity do on Jill?

Zero! She maintains her balance with ease! This implies she was never falling therefore the work gravity did on her was 0 since she was not moving up or down.

  • A) Brazil (The Macaw Conflict)

  • B) Australia (The Great Emu War)

  • C) South Africa (The Ostrich Offensive)

  • D) New Zealand (The Kiwi Skirmish)

B) Australia (The Great Emu War)
