Question

an objects location at a specific point in time *
motion
position
acceleration
distance
change in position *
displacement
velocity
acceleration
speed
variable that is manipulated (changed around) by the experimenter. *
constant
dependent
independent
residual

Explanation:

• For the first question: Position is defined as an object's location at a specific point in time. Motion is the change of position over time. Acceleration is the rate of change of velocity. Distance is a scalar quantity representing the total path length.
• For the second question: Displacement is the change in position (a vector quantity). Velocity is the rate of change of displacement. Acceleration is the rate of change of velocity. Speed is the magnitude of velocity (a scalar).
• For the third question: An independent variable is manipulated by the experimenter. A constant is a quantity that does not change. A dependent variable changes in response to the independent variable. A residual is the difference between the observed and predicted value in regression.

Answer:

1. position
2. displacement
3. independent
