Position, Speed/Velocity and Acceleration

Name and Period:

Speed that does not change

• zero m/s
• constant speed
• resting
• positive acceleration

Velocity:

• same as speed
• units are miles/hour
• only if speed is different than 0
• speed in a given direction

Frame of reference

• Newton define it as a logical instrument to judge speed and/or velocity
• a way to measure speed and/or velocity
• a background used to evaluate motion and/or speed
• a starting point to interpret the given data

Speed at a given moment in time

• Instantaneous speed
• Instantaneous velocity
• momentum
• slope of the line ds/dt

amount of distance traveled in a certain amount of time

• speed
• velocity
• momentum
• acceleration

Average Speed

• total distance divided by time
• adding and then dividing displacement by time
• total displacement divided by total time
• total distance divided by total time

graph that shows velocity of an object

• V/t graph
• S/t graph
• a/t graph
• x/t graph

change in velocity over time

• speed
• position
• acceleration
• instantaneous velocity

Mark all that correspond to this: x/t

• speed
• position
• motion
• acceleration
