Physics of Motion 1
A quantity with magnitude but no direction.
What is a scalar?
We do this when we make a y=mx+c graph out of a curve.
What is linearization?
When objects move at very high velocities, their lengths get shorter due to this this phenomenon.
What is length contraction?
What is an inertial frame of reference?
This diagram shows particle interactions over time and space.
What is a Feynman Diagram?
You add these by the head to tail method.
What are vectors?
You use this calculation to find the vertical component of a vector.
What is v sin(theta)=vx?
Nothing can travel faster than this.
What is the speed of light?
These tiny particles make up the particles in the centre of the nucleus.
What are quarks?
These laws sweep out equal areas in equal periods of time, but you must be focused on two points at once.
What are Kepler's First and Second Laws?
This formula for a force of nature is proportional to the product of the masses of two objects and inversely proportional to the square of the distance between them.
(Newton's Universal Law of Gravity)
The energy held in a 300Kg spherical elephant held 25m above the surface of Earth?
What is 7500J of GPE?
This is the rest energy equivalent to 1kg of matter.
What is 9x1016 J ?
This force keeps the electrons in orbit around the nucleus and is always attractive.
What is the electrostatic force?
These forces and accelerations acts towards the center of rotating objects large and small.
What are the laws of gravitation and the force of centripetal acceleration?
This vector quantity is the product of the force applied over time, and is represented by the area under a force-time graph.
What is Impulse?
(What is change in momentum)?
The vertical velocity of 1.768 kg cannon ball launched at a velocity of 2.0 m/s and an angle of 30o from the horizontal.
What is 1m/s?
You travel in a 110m long train at near the speed of light and pass through a 100m long tunnel. This phenomenon is the reason you disagree with a near-by trainspotter about exactly what happened.
What is simultaneity?
This force acts only at very short distances. Up close it is very attractive, but don't get too close or too far away, or it is highly repulsive.
What is the strong nuclear force?
This is an acceleration and a force that puts you in a spin.
What are centripetal (phenomena)?
You find this using the slope of the slope of the graph of the position of a ball rolling down an inclined plane.
What is acceleration?
This can be derived from the universal law of gravitation combined with the laws of circular motion.
What is Kepler's Third Law?
These are the particles of nuclear radiation in order of increasing penetrating ability.
What are alpha, beta, and gamma?
This is the PE equivalent that holds at least half of the existing U-235 together for about 4 billion years at a time.
What is binding energy per nucleon?
Muons and other high energy particles can only reach the earth's surface due to these phenomena, as described by this theory.
What are time-dilation and length-contraction as described by the special theory of relativity?
