QUESTIONS AND SOLUTIONS GRADED A+
◉ displacement.
Answer: the distance between the starting and ending points of an
object's motion
◉ three ways you can write a displacement vector.
Answer: - with a vector diagram
- as a magnitude angle pair
- as an x-y pair
◉ velocity.
Answer: speed with direction; vector quantity.
◉ magnitude of a velocity vector.
Answer: the speed of the object
◉ projectile.
Answer: any object moving through air that is affected only by
gravity
,◉ trajectory.
Answer: the path that a projectile follows
◉ parabola.
Answer: a special type of arch or bowl shaped curve that is the
trajectory of a projectile
◉ range.
Answer: is the horizontal distance that a projectile travels in the air
before touching the ground
◉ T/F Projectile motion is two-dimensional.
Answer: true ; both horizontal and vertical motion happen at the
same time, both speed and direction change as the projectile moves
in the air
◉ the horizontal and vertical components of a projectile's velocity
are (independent/dependent)?.
Answer: indepedent, the horizontal component does not affect the
vertical component and vice versa
◉ subscripts (x,y).
,Answer: tell you the direction of the motion
◉ two factors of a projectile that you can control.
Answer: speed and angle at which you hit it
◉ circular motion.
Answer: occurs when a force causes an object to curve in a full circle
◉ examples of circular motion.
Answer: - the planets orbiting the sun
- a child on a merry-go-round
- a basketball spinning on a fingertip
◉ rotates.
Answer: we say the object "rotates" about the axis, when the axis is
internal (inside the object)
◉ revolves.
Answer: an object "revolves" when it moves around an external axis
◉ linear speed.
, Answer: the distance traveled per unit of time (when an object
moves in a line)
◉ angular speed.
Answer: the amount an object in circular motion spins per unit of
time; describes either the rate of revolving or the rate of rotating
◉ the unit used for angular speed.
Answer: rpm (rotations per minute)
◉ formula for angular speed.
Answer: rotations or degrees ÷ time = angular speed
◉ each point on a rotating object.
Answer: has the same angular speed
◉ circumference is equal to...
Answer: the distance traveled during one revolution
◉ circumference formula.
Answer: 2πr
