Motion
Change in position of an object over time describe in terms of displacement, distance, velocity, acceleration, time, and speed
Displacement
a Vector quality that’s a straight line distance between start and endpoints/ Specifies distance and direction
Distance
a Scalar quantity that’s a mesure of how far apart objects are
Scalar
Quantities that have size or magnitude
Vectors
Quantities that have both size or magnitude and a direction
Velocity
The change of displacement per unit of time (Vector)
Average velocity formula
Vav = Change in displacement/Change in time
Speed
The change of distance per uniform of time (no direction scalar)
Average speed
The overall change of distance per unit of time without reference to its direction
Instantaneous speed
Speed at a particular instance or point in time
Force
interaction between two objects (Always in pairs) a push, pull, or twist
What do you measure force in?
Newtons
Mass
Amour of matter in object
Weight
Name given to pulling force of gravity on object
Independent variable
Variable that you change in an experiment
Dependent variable
Variable affected by change (thing you mesure)
Control
Things that remain the same throughout the experiment
