What is KE = ½ mv^2 or Ek = ½ mv^2?
In 1999, a Japanese game company Konami released a dancing rhythm game that is based on moving your feet by stepping on pressure-sensitive pads in timed with the beat.
(B)What is DDR (Dance Dance Revolution)?

(B) What is 3 cal?
As the Smart Bike proceeds to go uphill, based on the line graph, the power consumption of the motor and the hub:
(B) What increases in a line graph?
This type of jump is a fundamental plyometric exercise that develops explosive lower body power, vertical jump height, and athletic performance through rapid force production during jumping onto an elevated surface.
(C) What is a Box Jump?
If the Street Curling Rock were to carry a textbook the distance it would travel ________ than without the textbook.
(C) What is Farther?
According to Harvard Medical School’s archive, Dancing and the Brain, “Studies using PET imaging have identified regions of the brain that contribute to dance learning and performance.” These regions of the brain include:
(E) All of the above
[Double points for proper question] Calories burned are based on:
(1) Activity, (2) Duration, (3) Diet, (4) Age, (5) Gender, and (6)Weight
(C) How is activity, duration, age, gender, and weight related?
When the Smart Bike is on a 180-degree surface, based on the line graph, the power consumption of the motor and the hub:
(A)What remains the same in a line graph?
This muscle is mostly used when doing a squat.
(C) What is quadriceps?
It is a precision team sport where players slide 42Lb granite stones across an ice sheet towards a circular target. Often referred to as “chess on ice”.
(A) What is Curling?
Interpret this Python program (Note: port B = Arm motor; port F = Leg motor):
r x in range(10):
await light_matrix.write(‘1’)
motor.run_for_degrees(port.F, 360, -800)
await motor.run_for_degrees(port.B, 360, -800)
await runloop.sleep_ms(450)
(C) How are the arms and legs moving ten times?
Leo the Trainer is ready to do sit-ups. In its first position, the hub is facing ________ up.
(B) What is left-side up?
True or false. When a car is driven up a very steep hill, changing the gear shift will help make the engine work less hard while accelerating.
What is true?
Shifting to a lower gear increases your engine's torque (pulling power) at the wheels. This allows the car to climb the hill with greater ease and acceleration, preventing the engine from lugging, straining, or overheating.
[Double points for show work] Toastada the cat, who weighs 9.92 lbs, jumped up to a 3 footed counter just to lay down on your lap. She exerted this amount of potential energy.
(B) What is 40.3 J?
Ep = mgh
Ep = (9.92Lbs) x (9.81m/s^2) x (3.0ft)
Ep = (9.92Lbs/kg x 1kg/2.2Lbs) x (9.81m/s^2) x (3ft/m x 1m/3.3ft)
Ep = (4.5kg) x (9.81m/s^2) x (0.91m)
Ep = 40.17 J or ≈ 40.2 J
Your freewheeling vehicle weighs 305g and is traveling at a velocity of 70m/s. This amount of kinetic energy is exerted:
(C) What is 747.25 J?
Ek = ½ mv^2
Ek = ½ x (305g) x (70m/s)^2
Ek = ½ x (305g/kg x 1kg/1000g) x (70m/s)^2
Ek = ½ x (0.305kg) x (70m/s)^2
Ek = 747.25 J
