1d motion test Flashcards
motion
change in an object’s position
distance (m)
total change in an object’s position, doesn’t include direction in measurement
displacement (m)
net change in an object’s position, does include direction in measurement (the shortest distance between two points)
speed (m/s)
measurement of how much something’s position changes per unit time
magnitude
velocity (m/s)
measurement of how much something’s position changes per unit time, magnitude and direction
+ and - sign is the direction
delta (triangle)
change in
instantaneous velocity (m/s)
how fast an object is moving at a particular instant in time and the direction of the object’s motion
acceleration
rate of change in an object’s velocity per unit time
slope
measure of steepness of a line
intercept
where a line intercepts on the y or x axis
d-t graph
graph showing distance vs. time
v-t graph
graph showing velocity vs. time
force
a push or pull
