Energy & Roller Coasters
The potential energy and kinetic energy of the 2 kg ball when it reaches the absolute lowest point of the track. Start at 140m above ground.
What are 0 Joules and 2,744 Joules?
This is how momentum and impulse are fundamentally related to one another.
What is "impulse is equal to the change in momentum"?
These are the three primary ways to charge a neutral object.
What are Friction, Conduction (Contact), and Induction?
The physical phenomenon that serves as the root cause of all waves.
What is a vibration (or disturbance)?
The distance between the Earth and the Sun if it takes solar light 498 seconds to reach us at a speed of 3x10^8.
What is 1.494 x 10^11meters?
The potential energy of the 2 kg ball, which sits at a height of 55 meters.
What is 1,078 Joules?
To improve passenger safety during a collision, this is the specific variable in the impulse equation that safety features (like airbags) are designed to increase.
What is time? (Increasing time reduces the impact force).
If a positively charged rod attracts a balloon, these are the two possible charge states the balloon could have.
What are negative or neutral? (Neutral objects experience polarization and attract).
The fundamental difference in particle motion between a transverse wave and a longitudinal wave.
What is perpendicular vs. parallel? (Transverse particles move perpendicular to wave direction; longitudinal move parallel).
The acceleration of a car that smoothly increases its velocity from 15 m/s to 25 m/s over a span of 5 seconds.
What is 2m/s2
The kinetic energy of the 2 kg ball at peak B (95m), assuming it started from rest at the 140-meter mark.
What is 1,666 Joules?
The primary metric used to differentiate between an elastic collision and an inelastic collision.
What is the conservation of kinetic energy? (Kinetic energy is conserved in elastic, but lost in inelastic).
This type of circuit features only one single path for current to flow, meaning if one light goes out, they all go out.
What is a series circuit?
The physical reason humans are entirely unable to hear a massive explosion out in space.
What is because space is a vacuum and sound requires a medium to travel?
Neglecting air resistance, this is how long a rock will be in freefall if it is dropped from the top of a 125-meter cliff.
What is approximately 5.05 seconds?
The velocity of the 2 kg ball as it passes over peak B (95m). The starting point was 140m
What is approximately 40.8 m/s?
The momentum of a 143-gram baseball traveling at a blistering 44 m/s.
What is 6.292 kg·m/s?
This type of circuit keeps voltage constant across all branches, keeps all bulbs at the same brightness, and allows others to stay on if one burns out.
What is a parallel circuit?
The frequency and period of a wave system where exactly 2 waves pass by a fixed point every single second.
What are a frequency of 2 Hz and a period of 0.5 seconds?
The weight of a book on the Moon if its verified weight on Earth is 34.6 N.
What is 5.77 Newtons?
The fate of the ball's total mechanical energy as it travels along the track if we completely neglect air resistance.
What is it remains perfectly constant (or is conserved)?
The final velocity and direction of a 70 kg player skating west at 5 m/s after they tangle up with a 90 kg player skating east at 2.5 m/s.
What is 0.78 m/s moving West?
Removing this specific component from the provided circuit diagram would instantly cause every other resistor to stop working.
What is Resistor 1? (Because it is in series with the main voltage source before the parallel split).
If the temperature and medium of the air stay perfectly constant, this happens to the wavelength of a sound when you increase its pitch.
What is the wavelength decreases?
The torque applied by Joe when he exerts 12 N of force perpendicularly to the end of a 0.24-meter-long wrench.
What is 2.88 N·m?
