AP PHYSICS: Vector Components

Q: A projectile flies with a velocity of 750 km per hour at a 300 angle south of east: What is the magnitude of the eastward component of motion? A: The projectile is moving both eastward and south simultaneously. The eastward component of motion is determined by using an appropriate trigonometric function that relates theContinue reading “AP PHYSICS: Vector Components”

AP PHYSICS: Vector Components

When vectors are oriented away from the ( x ) and ( y ) axes, they can be evaluated using ( x ) and ( y ) components. These components can be linked together in a tip-to-tail fashion which yields the same results as the primary vector in question: It is useful to imagine theContinue reading “AP PHYSICS: Vector Components”

AP PHYSICS: Trigonometry and Vector Components

Q: A charged species traveling at a constant velocity ( v ) through a magnetic field ( B ) will experience a force if the direction of motion is at a 900 angle with the B-field. How can trigonometry be used to quantify this phenomena? A: The magnetic force ( Fm ) on the chargedContinue reading “AP PHYSICS: Trigonometry and Vector Components”

AP PHYSICS: The Unit Circle and Basic Trigonometric Functions

Imagine a bat hitting a baseball head on. The ball-to-bat force pair created upon impact is unbalanced; thus, after impact, the ball will sail outward in the opposite direction. What if, however, the bat-to-ball collision occurred at an angle? How would the magnitude of force imparted to the ball change? Answers to these types ofContinue reading “AP PHYSICS: The Unit Circle and Basic Trigonometric Functions”

MATHEMATICS: Is The Earth Really Round?

Disclaimer: The earth, according to current mathematical models and observations, is not flat. ROUND-EARTH MATHEMATICS : In determining the rotational speed of the earth, we must first assume that the sun is positioned an exceptionally far distance from the earth. If this were not the case, snow, water, and complex biological life would be non-existent.Continue reading “MATHEMATICS: Is The Earth Really Round?”
