Position and Motion
The progress of changing position.
What is motion?
p.13
The speed and direction of a moving object.
What is velocity?
p. 23
A measure of the distance an object travels per unit of time.
What is speed?
p.17
The changing speeds of distance-time graph are..
Slowing down, stopping, speeding up, average speed.
p. 22
A measure of the change in velocity during a period of time
What is Acceleration?
p.27
An objects distance and direction from a reference point.
What is position?
p. 9
speed changes in an object.
What is changes in velocity?
p.23
The rate of change of position in which the same distance is traveled each second.
What is Constant Speed?
p.18
The process of changing direction in a vehicle is...
The vehicle's velocity stays at a constant speed.
p. 28
The representative of acceleration.
What is arrows?
p.28
Point you choose to describe the location, or position of an object.
What is reference point?
p.9
The change of speed and direction.
What is velocity change?
p.23
Speed at a specific instant in time.
What is Instantaneous Speed?
p. 18
Speed-time graphs are different than distance-time graphs because...
Speed-time graphs have time in a horizontal line on the x-axis and speed is vertical on the y- axis.
p.30
Speeding up in a forward direction.
What is positive acceleration?
p.29
"Left" "up" "forward" "right" are describing what?
What is Reference Directions In Two Dimensions?
p. 12
The representive of velocity.
What is displacement shown by arrows?
p.23
The total distance traveled divided by the total time taken to travel that distance.
What is Average Speed?
p.19
Distance-speed are different than speed-time graphs because..
Distance-time graphs are curved instead of straight lines.
p.22
At every point in time, the speed is the same.
What is constant speed?
p. 31
The difference between the initial (first) position and final position of an object.
What is displacement?
p.13
Velocity is changed by..
What is change of direction?
p.23
How do you calculate Average speed?
Average speed (in m/s) = total distance (in/m)
total time (in s)
p.19
An object at rest is always..
What is speed at a constant zero?
p.30
Slowing down in the forward direction.
What is negative acceleration?
p.29
