(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.
(3) Balanced forces have either a push or pull that is __________.
Equal
Unequal
Hard
Easy
(4) John was blowing a feather across the dinner table. When he was blowing with all the breathe he had in him the feather went across the entire table, but when he just blew a little it only went to the edge of his plate. What statement best describes why the feather went across the table?
John used a strong blowing force causing the feather to travel a greater distance.
John used a weak blowing force causing the feather to travel a greater distance.
John used a pulling force to cause the feather to travel a greater distance.
John is a fire breathing dragon.
(7) Which scenario is showing gravity as the main force moving an object?
My pencil fell to the ground when I dropped it.
A plane taking off.
A feather floating in the wind.
A boy threw a ball up in the air.
(8) 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.
(10) The location of an object relative to another object (the reference point)describes the _______ of an object.
Distance
Speed
Position
(11) _______ is the force that opposes motion between two surfaces that are in contact with one another. This will cause the objects to pull and/or drag against one another.
Gravity
Lubrication
Magnetism
Friction
(12) The Sun’s gravity pulls ___________ into orbit.
Stars
Galaxies
Earth
Comets
(13) Samantha was trying to open a door. Each time she would pull on the door, it would make an awful noise and she would have to use a lot of force. How can she fix the problem so she doesn’t have to use as much force?
Add lubrication to the door to make the pulling force smooth.
Take away the lubrication to the door to make the pulling force smooth.
Add lubrication to the door to make the pulling force rougher.
Take away the lubrication to the door to make the pulling force rougher.
(14) Which material, when placed under a book, would best prevent the book from sliding off a table that is raised on an incline?
Glass plate
Silver tray
Poster board
Rubber mat
(17) Why are people advised to drive more slowly when it is raining?
Wet tires may make it difficult for cars to reach normal speeds.
Cars might stop too quickly and without warning.
The friction between tires and the road is increased.
The friction between tires and the road is decreased.

be pushed against the door on the driver's side
The gravity between two objects depends on the distance and ____________.
magnetic attraction
volume
mass
momentum
The planet Jupiter has much more mass than Earth. What is the weight of an astronaut who lands on Jupiter?
The astronaut would weigh more on Jupiter than on Earth
The astronaut would weigh somewhat less on Jupiter than on Earth
The astronaut would have the same weight on Jupiter as on Earth
The astronaut would be weightless on Jupiter
The force that keeps satellites in orbit around Earth is
magnetic
friction
electrical
gravity
What effect does friction have on a moving object?
it causes the moving object to slow and eventually stop
it causes the moving object to speed up
it keeps the moving object moving in the same direction forever
it causes the moving object to turn around and move in the opposite direction
When an object is sitting on the Earth, what do you call the force of gravity that is acting on the object?
weight
mass
magnetism
momentum

The equation F=ma relates to one of Newton's Three Laws of Gravity. Which law of gravity does it relate to?
Newton's First Law
Newton's Second Law
Newton's Thirds Law
Newton's second law of motion states that an unbalanced force that acts upon an object causes it to:
accelerate
not accelerate (keep the same velocity)
have a velocity
The bigger the unbalanced force acting on the object, the ______ the acceleration of the object.
bigger
smaller
The greater the mass of the object, the greater it is will resist a change in its motion.
True
