Particles
Name the 3 particles that compose an atom
Protons, Neutrons, Electrons
Correct pronunciation of "Nuclear"
New-Clear
Who is the father of modern physics, classical mechanics, and calculus
Issac Newton
A gym bro unracks a 100kg bar and benches it a distance of 0.2m down and re racks the bar, how much net work has he done? (work is force over distance)
Zero work, since the bar's final position is the same as its initial position the net work is 0
the steering wheel of your car controls its acceleration. T/F
True, Acceleration is a vector and has direction
What is the difference between visible light and gamma rays
wavelength
How many nuclear cores were made to be dropped on Japan in WW2
Three, Fat man, little boy, demon core
Why is it easier to open a door by pushing far from the hinges?
What is the difference between velocity and speed
velocity has direction
What is the Pythagorean theorem?
A squared plus B squared equals C squared
Is a photon a particle or a wave?
Yes.
Name 3 anti particles
Anti-Proton, Anti-Neutron, Positron, Anti-Neutrino
Instead of degrees, engineers use radians which are measured in what?
Pi
A spring is compressed, what happens to the work done to the spring.
The energy from the work is converted to potential energy stored in the spring
What is an irrational number?
A never ending decimal number like Pi or 10 / 3.
How is the mass of Helium 4 (2 Protons, 2 Neutrons) related to the mass of two free protons and two free neutrons.
The mass of Helium 4 is less than the mass of the sum of its individual particles. (Binding Energy)
Why is cold fusion impossible
Fusion requires an immense amount of energy to overcome coulombic repulsion
What is an engineering students favorite sentence? Assume __________
Assume no friction or air resistance.
What is the acceleration due to gravity on earth
9.81 m/s^2 or 32.2 ft/s^2
How many conditions of equilibrium are there for a 2D rigid body
Three. X and Y directions and rotational.
Explain why we can't know an electrons position and momentum at the same time (Heisenberg's Uncertainty Principle).
Observing an electron requires a photon to collide with it causing it to scatter.
Explain why we can't travel at the speed of light.
As your velocity approaches the speed of light, your mass and the energy required to accelerate approach infinity. (Special Relativity)
Momentum is dependent on what two variables
Mass and Velocity
Press the buzzer first
whoever buzzed first wins
Why is a perpetual motion machine impossible?
Dissipative forces like friction and air resistance, and runs with %100 efficiency.
