(2) Mrs. Giet’s class is playing tug of war at recess. They decide to play boys against girls. There are 11 girls and 6 boys. As soon as the game began, the girls were able to move the rope to their side. Why?
There was an equal amount of force pulling on each side making it unbalanced.
There was an equal amount of force pushing on each side making it unbalanced.
There was more force on the girls side making it unbalanced.
There was less force on the girls side making it unbalanced.
Which of the following best explains the motion of the car represented in section “D” of the graph?
The car is stopped in section “D”.
The car is going faster than it was in section “B”.
The car is moving on level ground in section “D”.
The car is higher than it was in section “B”.
What would most likely happen to the motion of the box if you poured oil on the ramp?
It will slow the box because the force of friction will be increased.
It will speed up the box because the force of friction will be increased.
It will slow the box because the force of friction will be reduced.
It will speed up the box because the force of friction will be reduced.
A student wishes to design an investigation to determine the effect of changing the mass of an object when an unbalanced force is applied to the object. What should she use as the independent variable in her investigation?
time
force
mass
speed
Which of the following best explains which material would work best for the warehouse floor?
The tile because it had the least friction.
The wood because it would be easiest to push the boxes on.
The dirt because it has the least friction.
The asphalt because it has the most friction.
A car was traveling on a dirt road and on a concrete road. The car was able to travel on the concrete road without using as much force. Which description explains this scientific fact?
The dirt road has more friction because the surface is not smooth.
The concrete road has more friction because the surface is smoother.
The concrete road has more gravity because the surface is not smooth.
The concrete road has less gravity because the surface is not smooth.
What is the best description of what happened between A and B?
The runner sat down.
The runner slowed down.
The runner sped up.
The runner crossed the finish line.
The diagram above shows four identical boxes filled with different materials that need to be pushed across the room. Equal force is applied to each box for 15 seconds. Which box will move the farthest after 15 seconds?
A. Box 1
B. Box 2
C. Box 3
D. Box 4
Why do the boxes move different distances when pushed with the same amount of force?
A. Lighter objects have increased friction with the floor.
B. Heavier objects have increased friction with the floor.
C. Smooth objects have more friction with the floor.
D. Rough objects have more friction with the floor.
What experimental tool would be most useful in this experimental investigation?
A. Hand lens
B. Spring scale
C. Calculator
D. Meter stick
A force can
A. make an object move
B. slow and object down
C. make a moving object stop
D. all of these

If these boys are pulling with the same amount of force. What will happen?
The boy in Image B has a harder time getting down the hill because...
motion is pulling him down
the friction between him and the ground is preventing him from going down the hill faster.
the friction is pushing him away from the hill.
the friction is preventing him from moving.
In an experiment, how many variable can you change in one time?
none
1
2 or more
depends on the type of experiment
While performing an experiment, it is important to:
change the control setup
test many different variables at the same time
reach a conclusion
record observations and measurements
Students used various temperatures of water to see which one dissolved candy faster.
What was the Independent Variable also known as the V?
Amount of Candy
Amount of Water
Temperature of Water
Time for Candy to Dissolve
An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the Result (R) is...
the type of plant.
the amount of sunlight.
growth of the plant.
the type of liquid.
A ball is kicked and rolls for a long distance across a field. Which force eventually causes the ball to slow and stop?
friction
gravity
motion
position
Alys stands at the top of a steep hill and pushes a ball over the edge with her foot. Which force causes the ball to continue rolling down the hill?
mass
gravity
friction
air resistance
Which example has the most friction?
The data shown in Figure 1.2 might support which of these hypotheses?
Brightly colored insects are harder for birds to catch.
Insects can hide to avoid bird predators.
Birds choose insects to eat based on their size.
Camouflage protects insects from being eaten.
Players from the Astros want to know who can throw a baseball the farthest. They mark off an area in the outfield to test their investigation. Which should they keep constant or stay the same, so they could have an accurate experiment?
height of the players
color of the balls thrown
order in which the players throw
spot from which the players throw
In an experiment testing different surfaces, Hannah is using a ramp and toy car to find out how friction affects the distance traveled. She will use carpet, wood and sand paper. She will also use a height of 2 cm, 3 cm and 4 cm for the ramp. It resulted that the sand paper had the greatest amount of friction. Is this correct?
It is correct because sand paper is very rough and creates a lot of friction when you rub against it.
It is incorrect because you have more that one variable which makes this experiment invalid.
It is correct because you can have several variables just as long as you do it carefully.
It is incorrect because carpet is a lot more rough than sand paper and creates a lot more friction.
Niki has a bag of 12 cm rubber bands. She wanted to test their resistance. She grabbed one and applied a force of 10N. It snapped. She then concluded that all 12 cm rubber bands will snap when you apply a force of 10N. Is this a valid conclusion?
Yes, because when you are doing an experiment, you only need to perform one trial.
No, because in order for a conclusion to be scientifically accurate you must perform at least 3 trials.
No, because everyone knows that rubber bands snap when you apply 20N of force.
Yes, because the day before he applied the same amount of force to 8 cm rubber bands and they snapped.
What is the dependent variable or R on the graph (y-axis)?
