True or False: A frame of reference is something that is not moving with respect to an observer that can be used to detect motion
True
Define instantaneous speed
The speed of an object at one instant in time
Define distance in your own words
Answers will vary but it should be somewhat along these lines: the length you traveled in all directions
Define velocity
The speed of an object in a particular direction
Define displacement in your own words
Answers will vary but it should be somewhat along these lines: the distance from your starting point to your stopping point (in a straight line), also needs direction
What is the formula for velocity?
Speed but ADD ON THE DIRECTION!!!!!!
Define motion in your own words
Answers will vary but it should be somewhat along these lines: a continual change in an object's position
Define acceleration
Speeding up, slowing down, or changing direction
or the rate at which velocity changes over time
What is the equation for speed, distance, and time?
speed = distance/time
distance = speed x time
time = distance/speed
Define terminal velocity
The highest velocity reached by a falling object. At this time, air resistance equals the weight of the falling object
