Foundations
A simplified, idealized representation of a physical system or phenomenon designed to make complex reality manageable and testable.
What is a model?
A standard, viewpoint, or coordinate system used to measure positions and motion.
What is a Frame of Refrence?
A physical quantity that has magnitude but no direction
What is a scalar?
An action exerted on an object that may change the object's state of rest or motion.
What is a force?
The displacement for a Gecko traveling 10 m up a tree, seeing a fly 2 m below, and moving 2 m downward to catch it.
What is eight meters?
Process where the first step is to make observations and collect data that lead to a question.
What is the scientific method?
The frame of reference for a car moving at a speed of 20 mph.
What is the road?
The process of adding the vertical and horizontal components of a vector.
What is resolving a vector?
An object at rest will remain at rest will remain at rest and an object in motion will remain in motion unless otherwise acted upon by an unbalanced force.
What is Newton's First Law?
The speed of the crash if a car is traveling down the highway at 50 m/s and crashes into another traveling at 30 m/s.
What is 20 m/s?
What historical figure wrote "Dialogue Concerning the Two Chief World Systems" wherein he disproves Aristotle’s claim that heavy objects fall faster than light objects.
Who is Galileo Galilei?
This is the net change in position from when you left for school this morning until you returned home
What is Zero?
The formula for Pythagorean Theorem.
What is a2+b2=c2?
Force is equal to mass multiped by acceleration.
What is Newton's Second Law?
The speed of 5.9 m/s converted into miles/hour
What is 13 miles/hour?
What is the derived unit which results from the base units (kg)(m)/(s2)
What is a Newton (N)?
The motion of a body when only the force due to gravity is acting on the body
What is free fall?
The degree of rotation for subtracting a vector
What is 180 degrees?
Every action has an equal and opposite reaction.
What is Newton's Third Law?
The net vertical force applied to a person accelerating at 1 m/s2 to the right.
What is Zero?
The number of significant figures resulting from the equation (1.2)(1.003)-(2.00-2.1)+3
What is One?
What is the missing term in the equation?
vf=[ ] + (a)(Δ t)
What is the initial velocity (vi)?
The mathematical representation of vertical component of the initial velocity with a direction of the angle θ above the horizontal.
What is the product of the magnitude of the initial velocity and the sine of angle θ (visin(θ)).
This force opposes the force of friction.
What is the applied force?
The magnitude and direction of the swimmer traveling at 10 m/s away from shore relative to the water she is in. The current is also traveling away from the shore, but also 30 degrees to the right, at 5.0 m/s.
`What is 15 m/s at 10 degrees to the right?
