### Question 1

Question
Pam ran down the sidewalk to school with her empty backpack. After school, Pam’s backpack was loaded with books. Which best describes the force required to carry her book bag home?
• It took the same amount of force to carry the loaded book bag home.
• It took a greater amount of force to carry the loaded book bag home.
• It took a lesser amount of force to carry the loaded book bag home.

### Question 2

Question
Sam is building a car to race down a ramp. The car weighs 100 grams. Which could Sam do to increase the speed of the car?
• increase the mass of the car
• decrease the mass of the car
• increase the friction on the ramp

### Question 3

Question
How does friction affect speed?
• more friction decreases speed
• more friction increases speed
• less friction decreases speed

### Question 4

Question
Tamara and Justin are racing on the playground. Tamara runs the distance from the basketball goal to the jungle gym in 45 seconds, while Justin runs the same distance in 52 seconds. Which best describes the movement of the students?
• The students ran in different directions.
• Both students ran at the same speed.
• Tamara ran faster than Justin.

### Question 5

Question
A girl walked for 30 minutes. She noticed that she traveled farther in the first 15 minutes of her walk than in the second 15 minutes. What can she conclude about her walk?
• She walked over many hills.
• Her average speed was faster during the first half of her walk.
• She walked in two different directions.
• She was walking at a constant speed.

### Question 6

Question
James and Roy compare the motion of two balls by rolling them across the floor and recording the time it takes them to travel the same distance. Ball X travels the distance in 15 seconds. Ball Y travels the distance in 11 seconds. Which best compares the motion of the two balls?
• Ball X travels faster than Ball Y.
• Ball Y travels faster than Ball X.
• Both balls travel at the same speed.
• Both balls travel at a constant speed.

### Question 7

Question
Which best describes the force of gravity?
• a pulling force
• a pushing force
• a change in mass
• a change in speed

### Question 8

Question
When is friction needed during the course of motion?
• to speed up motion
• to slow down motion
• to keep motion at the same speed
• to keep motion in the same motion

### Question 9

Question
Based on the graph, what can be inferred about the speed of the vehicle?
