Displacement
________ is a vector that accounts for both distance (between initial and final positions) and direction measured in meters (m).
New cards
5
Direction
Distance is the total movement of an object without regards to ________.
New cards
6
Not equal
Displacement does ________ displacement because displacement measures the shortest distance between the start and end point while distance measures the total length traveled.
New cards
7
Speed
________ only indicates how fast an object is moving.
New cards
8
Displacement
Average velocity = ________ / time
New cards
9
Instantaneous
________ velocity indicates how fast and in what direction an object moves at a certain instant of time.
New cards
10
Magnitude
Instantaneous speed is the ________ of instantaneous velocity.
New cards

meters per second squared
Acceleration is a vector of the rate of change of velocity over time measured in ________ (write it out in words).
New cards
12
Decelerates
An object ________ whenever the acceleration and velocity vectors point in opposite directions, causing the object to slow down.
New cards
13
Drawing
The first step in solving a kinematics problem is making a ________. This will help you visualize the motion and make sense of any positives or negatives.

Near Earth’s surface, the magnitude of acceleration due to gravity is roughly _______ meters per second squared.
New cards
17
Time
________ symmetry of freely falling bodies states an object will take the same amount of time to go up as down.
New cards
18
Speed
________ symmetry of freely falling bodies states an object falling down travels at the same speed it would have going up at the same height.
New cards
19

On a _______ vs. time graph, the slope is acceleration.
New cards
21
