In a science lab, students measured how long it took for a block to slide down a ramp. What were the students comparing in this experiment?
the amount of frictional force acting on the block
the amount of gravitational force acting on the block
the amount of frictional force acting on the ramp
the amount of gravitational force
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
Vincent is playing catch with a friend. When Vincent throws the ball, it travels in an arc-shaped path. The path of the ball is arc-shaped due to the force of Vincent's throw and what other force?
friction
gravity
inertia
magnetism
Allen pushes a toy car across three different surfaces. He pushes the car across a wooden floor, tile floor, and a carpeted floor. He notices it is hardest to push the toy across the carpeted floor. Which is the MOST likely reason it is hardest to push the car across the carpet?
the car has more mass when it is on the carpeted floor.
the carpet creates more friction than the other surfaces.
the car is affected most by gravity on the carpeted floor.
the carpet pushes more against the car than the other surfaces.
Ari had one ball and two ramps. The ramps were identical except that one had a sandpaper surface and one had a plastic surface. Ari measured how long it took the ball to roll down each ramp. Ari MOST likely was investigating the effect of which force on the speed of the ball?
electricity
friction
gravity
magnetism
Adrian makes a ramp out of some books and a plank of wood. He can change the height of the ramp by adding books under the plank. He rolls a toy car down each ramp. At the bottom of which ramp would the car be traveling the fastest?
A
B
C
D
Two balls rolled down two identical inclined planes. The balls were exactly the same mass and size, but one ball rolled down the inclined plane faster. Identify a possible reason that one ball rolled faster than the other ball?
one ball was red and the other ball was blue
one ball was new and the other ball was old
one ball was shiny and the other ball was dull
one ball was sticky and the other ball was smooth
A student uses a rubber band to launch the four objects listed in the answer choices. If the student pulls the rubber band back the same amount each time, which object will MOST LIKELY move the fastest when launched?
paper clip
piece of paper
eraser
rubber ball
Four cars are at the starting line of a race. Which car will require the MOST FORCE to start moving?
a car with mass of 1200 kilograms
a car with mass of 1500 kilograms
a car with mass of 1700 kilograms
a car with mass of 2000 kilograms
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
Which surface will MOST LIKELY cause a rolling ball to slow down?
grass
ice
tile
How does friction affect speed?
more friction decreases speed
more friction increases speed
less friction decreases speed
Carey left a bowling ball and a kickball outside on a windy day. Which BEST explains why the kickball moved but the bowling ball did not?
the kickball has less mass so it was easier to move
the force of gravity acting on the bowling ball is greater
the mass of the kickball is greater so it is easier to move
Which is an example of trying to increase friction?
spreading sand onto an icy road
reducing the weight of an object
pouring oil into the engine of a car
waxing the underside of a surfboard
Why is it important for basketball players to wear shoes with tread when playing?
to increase the speed of the player
to decrease the force between the player and the floor
to increase friction between the floor and the player's feet
to decrease the amount of force needed for the player to move
Which BEST describes the relationship between movement and friction?
as the rate of friction increases, the rate of movement increases
as the rate of friction increases, the rate of movement decreases
as the rate of friction decreases, the rate of movement increases
as the rate of friction decreases, the rate of movement is unchanged
In order for someone to push a heavy box 10 meters across a floor, which must happen?
the force of the person pushing must be greater than the force of friction
the force of the person pushing must be less than the force of friction
the force of the person pushing must be less than the force of gravity
the force of the person pushing must be greater than the force of gravity
How would the absence of friction affect a marble traveling on a long, straight path?
the marble's speed would decrease
the marble's speed would increase
the marble would stop immediately
the marble would remain at constant speed
When Anna tells her father that her bicycle is hard to pedal, he oils the chain. How does this make her bike easier to ride?
friction on the bike has increased
friction on the bike has decreased
gravity on the bike has increased
gravity on the bike has decreased
