Position
Where an object is, in terms of a well-chosen origin.
Path Length
How far an object actually moves
Displacement
An object's change in position
Speed
How fast
Always positive
Velocity
Displacement over time
Acceleration
Change in velocity / Time
Positive vs. Negative Velocity
Tells you the direction of travel
Positive Acceleration
Speeding up in positive direction
Slowing down in negative direction
Negative Acceleration
Slowing down in positive direction
Speeding up in negative direction
Slope of Velocity vs. Time
This slope equals acceleration
Slope of Position vs. Time
This slope equals velocity
Area of Acceleration vs. Time
This area equals change in velocity
Area of Velocity vs. Time
This area equals change in position
Horizontal Variables
Horizontal Kinematic Equations
Vertical Variables
Vertical Kinematic Equations
Free Fall
The only force on an object is gravity
Acceleration due to Gravity
On Earth, -9.8 m/s2
Vector
Has both magnitude and direction
Scalar
Has only magnitude (just a number)
Resultant
The answer to a vector addition problem
Pythagorean Theorem
Used to add together perpendicular vectors
Negative of a Vector
Flips the direction of a vector
Projectile
An object that is thrown or launched
Parabola
The shape of a projectile's trajectory
Trajectory
The path an object follows
Complementary Angles
Add up to 90 degrees
Incline
A ramp
Distance
The absolute value of displacement
