What is average velocity?

Average rate of change of the position function

What is average acceleration?

Average rate of change of the velocity function

What is displacement?

Change of position over time

How do you find the particles greatest speed?

Find the highest y value of the absolute value of the velocity graph

How do you find the total distance traveled over a given time?

Make a chart up to the given time and find the difference of the y values, then add those numbers together

How do you describe the motion of a particle over a given time?

Make a table of the velocity function up to the given time and then determine over what values the particle moves left, right, or still

How do you graph the speed graph?

Move all parts of the function that are below the x axis so that they are flipped above

How do you find acceleration over a given time

Plug in the given time into the acceleration equation

How do you find the velocity after a given time?

Plug the given time into the velocity function

Velocity is the derivative of what?

Position

How do you find the displacement over a given time?

Set the position equation equal to 0 and equal to the given time, then subtract the two

How do you find when the particle is at rest?

Set the velocity function equal to 0 and solve

What is the absolute value of velocity?

Speed

What is the total distance traveled

Sum of all the movements of and object over time

When velocity equals 0?

The object is at rest or changing direction

Acceleration is the derivative of what?

Velocity

When an object is moving left?

Velocity is negative

When an object is moving right?

Velocity is positive

When does a particle move at its greatest speed?

When the slope is the greatest

When is the particles acceleration 0

When the slope of the velocity equation is 0

When is the particles acceleration negative?

When the slope of the velocity function is negative

When is a particles acceleration positive?

When the slope of the velocity function is positve

When is the particle at rest?

When the velocity equation crosses the x axis

When is a particle moving forward?
