physical science
acceleration
a change in speed, direction, or both; rate of change in velocity
free fall
movement of an object toward Earth because of gravity alone
constant acceleration
steady change in speed, direction, or both (velocity)
linear graph
displayed data forms straight-line paths (slope is acceleration)
nonlinear graph
a curve connects the points that are plotted
increasing velocity
positive; acceleration
decreasing velocity
negative; deceleration
acceleration graph
x axis: time, y axis: velocity, line: acceleration
instantaneous velocity
velocity at a specific moment
constant velocity
steady change in velocity over time
