25% 25%25%25%A. A change in mass over time

B. A change in position over mass

C. A change in distance over time

D. A change in mass over distance

How do you know that the car is in motion?

We are learning to: explain the difference between speed and

velocity

We are looking for: Speed = change in distance/ change in time. Velocity

= speed + direction of an object. Velocity has a direction, while speed

does not.

What is the formula needed to calculate speed of an object?

distance x

tim...

distance / ti

m...

time / dist

anc...

acceleration x.

Joe Shmoe walks 30 meters in 10 seconds. What was his speed?

25% 25%25%25%

A. 5 meters/secondB. 3 seconds/meterC. 3 meters/secondD. I need help!

What is the only difference between speed and velocity?

20% 20% 20%20%20%

A. Speed is more complex while velocity is less complex.

B. Velocity is time divided by distance and speed is distance divided by time.

C. Velocity requires a direction while speed does not.

D. Speed and velocity are calculated differently.E. I need help!

Which of the following is an acceptable unit for velocity?

A. Meters per secondB. Feet per hourC. Miles per hour SouthD. Miles per hourE. I need help!

Please copy circle and do this.

Speed

• Fill in three words that closely relate to the one word given.

• Write a paragraph explaining the significance of each word and how they fit together to form a concept?

We are learning to: explain the difference between speed and velocity and interpret

graphs.

We are looking for: Speed = change in distance/ change in time. Velocity =

speed + direction of an object. Velocity has a direction, while speed does not.

You are asked to create a graph that shows the speed of an object. What should be plotted on

the x and y axes?

A. Y axis = speed; X axis = timeB. Y axis = time; X axis = distanceC. Y axis = distance; X axis = timeD. Y axis = time; X axis =

acceleration

What is this graph showing?

A. A person walking at varying speeds.B. A person walking at a constant

speed and then stopping to rest.C. A person standing still.D. A person walked three miles.

What does this graph show?

A. The object is not moving.

B. The object is moving at a constant speed.

C. The object is moving at a constant speed then stopped to rest.

D. The object is moving at varying speeds.

Distance

0 TimeD

What does a steep slope of a line on a distance time graph indicate?A. Speed is fastB. Speed is slowC. The object is not

movingD. Speed is changing

Graphing ActivityConstruct a graph in your notes using the data to the right. Be sure to label the x and y axis with correct units.
