Pg.11

What is Speed?

100

A measure of the distance an object travels per unit of time.

What is Speed?

Pg. 17

200

You can calculate speed by dividing the _____ traveled by the time it takes to go that distance.

What is distance?

Pg. 17

300

The rate of change of position in which the same distance is traveled each second.

What is constant speed?

Pg.18

400

Average Speed Equation.

What is V = d/t?

Pg. 19

500

The total distance traveled divided by the total time taken to travel that distance.

What is average speed?

Pg. 19

Velocity

100

The speed and the direction of a moving object.

What is velocity?

Pg. 23

200

The length of a arrow indicates speed. A greater speed is shown by a ____ _____.

What is a longer arrow?

Pg.23

300

Velocitas

What is the latin root for velocity?

Pg. 23

400

True or False : Velocity changes when the speed of an object, when the direction the object moves changes, or when both the speed and the direction change.

What is True?

Pg. 23

500

The velocity of a ball changes continually because both the ____ and the ______ of the ball change as the ball bounces.

What is speed and direction?

Pg.23

Acceleration - Changes in Velocity

100

A measure of the change in velocity during a period of time.

What is acceleration?

Pg. 27

200

An object accelerates when its velocity changes as a result of ________ speed, _________ speed, or changing direction. 

What is increasing and decreasing?

Pg.27

300

Like velocity, acceleration has a direction and can be represented by a _____.

What is a arrow?

Pg. 28

400

An acceleration arrow's direction depends on whether velocity ________ or _______. 

What is increases and decreases?

Pg. 28

500

When velocity decreases, _________ and ________ are in opposite directions. 

What is acceleration and velocity?

Pg. 28

Calculating Acceleration

100

Acceleration is a change in ______ divided by the time interval during which the velocity changes.

What is direction?

Pg.29

300

The thought of as speeding up in the forward direction.

What is positive acceleration?

Pg.29

400

The thought of slowing down in the forward direction as well as speeding up in the reverse direction.

What is negative acceleration?

Pg. 29

500
