The chart below shows four identical wagons loaded with different amounts of bricks. If the same amount of effort is applied to all four identical wagons, why would Wagon W move farthest?
It has the least amount of mass, affecting its motion
It has the least amount of speed, affecting its motion.
It has the greatest amount of gravity, affecting its motion.
It has the greatest amount of friction, affecting its motion.
Ana is pushing a wheelbarrow of rocks. She stops and unloads half of the rocks. How will this effect the force needed to move the wheelbarrow?
Gravity is increased, making the wheelbarrow easier to move.
Gravity is decreased, making the wheelbarrow harder to move.
Friction is increased, making the wheelbarrow harder to move.
Mass is decreased, making the wheelbarrow easier to move.
Katie was pulling a sled with her puppy in it. Katie's sister then got into the sled with the puppy. How would the sled's speed most likely change after Katie's sister got into the sled?
The speed would increase due to the change in mass.
The speed would decrease due to the change in mass.
The speed would increase due to the change in friction.
The speed would decrease due to the change in gravity.
What has the greatest impact on a free-falling object?
friction
gravity
inertia
momentum
Billy rolls a toy truck filled with marbles across the kitchen floor. He then dumps the marbles before rolling it back to his starting location. How would the speed of the truck most likely change on the way back?
The speed would increase due to friction.
The speed would increase due to a change in mass.
The speed would decrease due to a change in mass.
The speed would decrease due to a change in gravity.
Chris attaches a sheet of sandpaper to the top of his skateboard. How does this sandpaper most likely affect Chris's skateboarding?
It protects the skateboard from any damage.
It allows Chris to steer the skateboard in a variety of directions.
It reduces the effect gravity has on the skateboard as he moves down the ramp.
It increases friction between the skateboard and Chris's foot to keep him from slipping.
Four cubes made of different materials are moving down a plastic slide. Which cube would experience the greatest amount of friction?
the cube made of ice
the cube made of sandpaper
the cube made of smooth plastic
the cube made of polished stone
The gravitational force of the Sun is strong enough to hold all the planets of the solar system in orbit many millions of miles away. Which BEST describes why objects having far less mass on the surface of these planets are not pulled off and into the Sun?
The objects have too little mass to be affected by the Sun
The objects have more mass on the planets than on the Sun
The objects are held by the greater combined gravity of all the planets.
The objects are more strongly affected by the gravity of the planet on which they are found.
Students rolled a 22-gram car down three different ramps. The results from the investigation are shown in the table. Which statement BEST explains why the car rolled down the wood ramp the fastest?
There was more force applied to the car on the wood ramp.
There was less friction on the surface of the wood ramp.
The wood ramp was higher than the other ramps.
The car on the wood ramp had more mass.
Students set up the investigation shown. What can the students do to increase the speed that the marble will roll down the ramp?
add a layer of carpet to the board
lower the height of the board
use a longer board for the ramp
replace the board with a. smoother board
Which investigation will BEST test the effects of gravity on moving objects?
pencils falling from the same height
balloons floating upward from the same height
a bicycle speeding up on a flat surface
a ball slowing down on a flat surface
Brandon made a parachute for his action figure by taping a thin plastic sheet to pieces of string. Brandon tied the strings to the action figure. When he threw the action figure in the air, it fell back to the ground quickly. What can Brandon do to make the action figure fall to the ground more slowly?
use shorter pieces of string
use a larger sheet of plastic
add weights to the action figure
throw the action figure higher into the air
Jan has two identical magnets on her metal cabinet. She hangs a drawing using Magnet 1. She tries to hang a calendar using Magnet 2, but the calendar falls to the floor. Which BEST explains why Magnet 1 can hold up the drawing but Magnet 2 is unable to hold up the calendar?
The area near Magnet 1 has extra metal.
The calendar is longer than the drawing.
The area under Magnet 2 has more gravity.
The calendar has a greater mass than the drawing.
A rocket is traveling toward space. What force must the rocket act against as it move away from Earth?
inertia
gravity
magnetism
momentum
Miguel sorted objects he wanted to recycle into two similar boxes. He filled Box 1 with empty bottles and Box 2 with newspapers. He pushed both boxes across the floor. Miguel used more force to push Box 2 than Box 1. Which is the MOST likely reason Miguel used more force when he pushed Box 2?
Box 2 was taller than Box 1
Box 2 was heavier than Box 1
Box 2 had stronger sides than Box 1
Box 2 contained more objects than Box 1
Two people need to move a large, heavy box. One person pushes the box, while the other person pulls the box. Which way of moving the box makes the work easiest for the people?
Tina washes her hands with a bar of soap. When she gets the soap wet, it becomes very slippery. What force decreases as the soap becomes wet?
electricity
friction
gravity
magnetism
A ball rolled toward Manny while he was playing soccer. If Manny's foot kicks the ball as shown in the picture, which will MOST likely happen to the ball?
The ball will stop rolling
The ball will roll toward the east
The ball will continue rolling west.
The ball will go straight up the air.
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.
Four different students take turns pushing a large, heavy ball on the school parking lot. What is the BEST way to determine which student used the most force to push the ball?
compare the sizes of the students
compare the ages of the students
compare the distances that the ball rolled
compare the number of times the ball was rolled
Which investigation BEST measures the gravitational force on a toy car?
rolling the car down a steep ramp and measuring time
using a spring scale and measuring the weight of the car
pushing the car and measuring how far it travels before it stops
throwing the car in the air and measuring how far it goes before coming down

tilt the board to the left
tilt the board to the right
raise the end of the board
lower the end of the board
