A. What material is the ramp made of?
B. Which toy car looks the best?
C What effect does gravity have on a toy car?
D. What metal makes the best toy cars?
2. By changing the surface over which the car rolls from sandpaper to wax paper, you might be able to test the effect of what force?

B. Wind
C. Wind
D. Friction
(16) A ball has two forces acting on it. One force is pushing it to the left, and a larger force is pushing it to the right. In which direction will the ball move?
Right
Left
Up
Down
Amanda is rolling a cart down a ramp to see how fast the cart travels. How can she change the experiment so the cart will go faster when it reaches the end of the ramp?
Start the cart half-way down the ramp
Build a taller ramp
Add sandpaper to the surface of the ramp
Build a lighter cart
A student compares the amount of force used by his classmates to push a toy car down a ramp. What would be the best way to compare this force?
Measure the distance each time the car comes to a stop
Measure the amount of time it takes the car to travel down the ramp
Measure the distance the car travels with each push
Measure the amount of time it takes for the car to come to a stop
Samuel rolled four different balls across a table. All of the balls were the same size, but each had a different mass. The table shows the mass of each ball. Samuel rolled each ball with the same amount of force. Which ball most likely rolled the farthest?
ball 1
ball 2
ball 3
ball 4
A man is bowling at his neighborhood bowling alley. The bowling alley has lanes in which bowlers roll their balls down a long, narrow, wooden path trying to knock down ten large, white pins at the end. The wooden lanes have wax on them. Why might they put wax on the wooden lanes?
The wax reduces the friction and makes it easier for the ball to roll
The wax makes the lanes shiny
The wax makes the lanes bumpy and harder to aim at the pins
The wax makes the ball roll slower because it increases friction on the ball
A boy took his dog for a walk. The dog saw a rabbit, and decided to chase it. The dog drug the boy until he got tired and stopped. What can be said about the dog's force in comparison to the boy's force while the dog was chasing the rabbit?
Greater push
Smaller push
Greater pull
Smaller pull
What would happen to a seesaw if two 80 pound students got on each side of the seesaw?
The seesaw would stay balanced and not move
The two students would go up in the air
The one student would go up in the air
All of the children would fall off
What would probably happen if a boater pushes the water away from the boat with oars or paddles?
The boat will remain still, only the water will move
The boater will make the boat rock because of the waves
The boat will move away from the water that is being pushed by the oars
/the boat will turn over, or capsize
Two students sit on a seesaw in a way that makes it balance and not move. When a third person pushes on on one side, that side moves down. What caused the seesaw to move?
The effect of gravity increased when one side was pushed down
The friction between the two sides decreased because of the push
The total force increased on the side that was pushed down
The push on one side of the seesaw decreased the force on the other side.
When one of the balls on a Newton's cradle is pulled back and released on one side, one ball on the opposite side moves. What would happen if two balls were pulled back and released?
Only one ball would still move on the opposite side
Two balls would move on the opposite side
No balls would move on the opposite side
All of the balls would begin moving and swaying
A student is investigating the effect of force on several objects. If each ball is rolled with the same amount of force on the same surface, which ball will roll the farthest?
Golf ball-48 grams
tennis ball-58 grams
Soccer ball-420 grams
Basketball-600 grams
golf ball
tennis ball
soccer ball
basketball
Unit of force is
millimeter
Joule
Newton
Cohesion
A girl riding a bike on flat ground comes to a hill. Why does she have to pedal harder as she makes her way up the incline?
She changed direction
She is working against gravity
She stopped moving
Wind resistance is greater
A boy is pulling his little sister in a wagon. If his older brother comes along and they pull on the wagon together, how will this increase in force affect the motion of the wagon?
It will accelerate
It will change direction
It will continue unchanged
It will stop moving
A student shoots a basketball. Which non-contact force drags the ball down as it arches towards the basket?
Friction between the ball and air
The ball hitting the rim before bouncing in
Gravity pulling the ball towards Earth
The student pushing the ball into the air
According to Newton's 3rd Law, forces always occur in _______ pairs.
Equal but complimentary
Equal but opposite
Unequal but opposite
Unequal but complimentary
An object will be easier to move if the __________ is greater
friction
distance
speed
force
We have seen the warning "Slippery When Wet" in most public places. A type of force is weakened when the floor is slippery. Which type of force is that?
Gravitational
Inertia
Mechanical
Frictional
If you throw a ball across a field, which forces are most likely to cause it to stop?
Wind resistance and magnetism
Inertia and Magnetism
Friction and gravity
Gravity and inertia
Two students want to see who was better at tug of war. What can be said about the force applied by the student who won?
He applied a greater push
He applied a smaller push
he applied a greater pull
He applied a smaller pull
