General Physics Exam 1 || with A+ Guaranteed Solutions.
motion correct answers change of an object's position or orientation with time
trajectory correct answers The path along which an object moves, which might be a straight line or might be curved
motion diagram correct answers a series of images showing the positions of a moving object at equal time intervals
model correct answers highly simplified picture of reality
particle correct answers An object that can be represented as a mass at a single point in space
particle model correct answers a simplified motion diagram that shows the object in motion as a series of points
position correct answers location at a particular instant in time
origin correct answers A fixed reference point
displacement ∆x correct answers the change in position of an object; the difference between a final position xf and an initial position xi.
time intervals correct answers changes in time
uniform motion correct answers motion at a constant speed
Speed correct answers measures only how fast an object moves
velocity correct answers tells us both an object's speed and its direction
scalar quantity correct answers A physical quantity is described by a single number, can be positive, negative, or zero
vector quantity correct answers a quantity that has both size and direction
magnitude correct answers Size or length of a vector
displacement vector correct answers A vector that spans the object's displacement in the direction of travel
True correct answers True or False: An object's displacement vector is drawn from the object's initial posi- tion to its final position, regardless of the actual path followed between these two points.
