FPC Chapter 11 - Motion
frame of reference - ANS-a system of objects that are not moving with respect to one another
relative motion - ANS-movement in relation to a frame of reference
distance - ANS-the length of the path between two points
vector - ANS-a quantity that has magnitude and direction
resultant vector - ANS-the vector sum of two or more vectors
speed - ANS-the ratio of the distance an object moves to the amount of time the object moves
average speed - ANS-the total distance traveled divided by the time it takes to travel that
distance
instantaneous speed - ANS-the rate of which an object is moving at a given moment in time
velocity - ANS-the speed and direction in which an object is moving
acceleration - ANS-the rate at which velocity changes
free fall - ANS-the movement of an object towards Earth solely because of gravity
constant acceleration - ANS-a steady change in velocity
linear graph - ANS-the displayed data form straight-line parts
nonlinear graph - ANS-a curve connects the data points that are plotted
