This quantity describes how fast an object changes its velocity over time.
What is acceleration?
This is the rate at which an object moves from one place to another.
What is speed?
This quantity includes both an object's speed and its direction.
What is velocity?
This is the total length of the path an object travels.
What is distance?
This is the straight-line change in an object's position from start to finish.
What is displacement?
This graph shows an object's position as time passes.
What is a position-time graph?
The slope of a position-time graph represents this quantity.
What is velocity?
This graph shows how an object's velocity changes over time.
What is a velocity-time graph?

What is Δx = vit + ½at²?
This equation relates final velocity, initial velocity, acceleration, and displacement without using time.
What is vf² = vi² + 2aΔx?
This equation calculates displacement using the average of the initial and final velocities.
What is Δx = ½(vi + vf)t?
This acceleration is approximately 9.8 m/s² downward near Earth's surface.
What is acceleration due to gravity (g)?
This mathematical theorem is used to calculate displacement when motion occurs at right angles.
What is the Pythagorean Theorem?
When analyzing motion, this is the first question you should ask about the graph according to the notes.
What is "Is the motion positive (above zero) or negative (below zero)?"
