An equilibrant vector is a vector that is the exact opposite of some other vector in both magnitude and direction. The simplest example of an equilibrant vector involves a single vector paired with its opposite: If the vector pair above represents two opposing forces, the net effect of being paired together is a cancellation thatContinue reading “AP PHYSICS: Finding The Equilibrant Vector”

Q: An ant travels long distances each day in search of food. On one such occasion, the ant travels 3.0 meters at an angle of 300 north of east. Afterward, the ant travels 2.0 meters to the north. Finally, the ant finds food after traveling 2.0 meters at an angle of 600 south of west.Continue reading “AP PHYSICS: Vector Addition”

Q: A football is kicked with a velocity of 8.5 m/s at an angle of 350 with respect to the football field: At the moment of takeoff, the football has a vertical component of motion of 4.9 m/s. What is the horizontal component of motion? A: Since an angle and a diagonal vector have beenContinue reading “AP PHYSICS: Trigonometry vs The Pythagorean Theorem”

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”

A scalar quantity is one that is dimensionless in terms of direction and is expressed in terms that communicate their magnitude. Energy and time are two great examples of such. On the other hand, there are vectors. Unlike scalar quantities, vectors possess both magnitude and direction. For example, an object can be considered to travelContinue reading “AP PHYSICS: Vector Addition and Subtraction”
