Sally and Lacy are racing hotwheels down different sloped ramps. Sally's car traveled down Slope A, and Lacy's traveled down Slope B. Sally's car traveled further than Lacy's. Why did Sally's car travel further than Lacy's?
Sally's car traveled further because her ramp was steeper, allowing her vehicle to pick up less speed.
Sally's car traveled further because her ramp was steeper and allowed her vehicle to pick up more speed.
Sally's car traveled further because her ramp was more shallow and allowed her vechicle to pick up less speed.
Sally's car traveled further because her ramp was steeper, allowing her vehicle to pick up less speed.
Which of these has the most speed and energy?
A car parked in a Wal-Mart parking lot
A dog laying in his bed
A lego sitting on a shelf
A go-cart driving down the raod
Jacob ordered two bowling balls of the same size and type. He bought green ball and one blue ball. Jacob rolled each ball down the same lane at the bowling alley one time while a friend used her phone timer to measure the time it took for the two bowling balls to travel to the end of the lane. After rolling both bowling balls down the same lane one time, they noticed that the blue ball made it to the end of the lane faster than the green ball.
Which is the most likely reason that the blue ball moved faster than the green ball?
the blue ball experienced less friction than the green ball
the blue ball had a higher magnetic charge than the green ball
the blue ball was more attractive than the green ball
The blue ball had more force applied to it than the green ball
A dog trainer designed a device to launch a dog treat into the air for a dog to catch. The device launches the treat when a weighted ball is dropped on the lever. The trainier wants to be able to launch the dog treat 5 inches in the air. Which set of steps should the dog trainer follow to make sure the device launches the treat to the correct heigth.
1. Drop the weighted ball
2. Listen for a sound
3. Replace the weigthed ball with something that weighs the same
4. Repeat all the steps untill the treat reaches exactly 5 inches
1. Drop the weighted ball
2. Measure how high the treat reaches
3. Replace the weigthed ball with something that has a different shape
4. Repeat all the steps untill the treat reaches exactly 5 inches
1. Drop the weighted ball
2. Add electrical energy to the system
3. Replace the weigthed ball with something that weighs the same
4. Repeat all the steps untill the treat reaches exactly 5 inches
1. Drop the weighted ball
2. Measure how high the treat reaches
3. Adjust th energy of the weigthed ball by holding it at different heigths
4. Repeat all the steps untill the treat reaches exactly 5 inches
A student is learning how forces act on a bridge. The task is to design a paper bridge that can support the greatest number of toy cars. The student must only use these materials: 1.) one piece of copy paper, 2.) four books (two on each side, 20 centimeters appart) 3.) up to 30 toy cars.
The student places 10 toy cars on the bridge and it collapses. Select the part of the design that most likely needs to be changes to improve the deign of the bridge.

A student observes 2 kids on the playground playing. A little boy is pushing the little girl on the swings. The student wants to measure how the force impacts how high the girl swings. The girl wants to reach a heigth of 4 feet in the air. The students want to describe the pattern of this motion. Which TWO measurements can the students use to describe the pattern?
the heigth of the bottle boy
the air temperature at the park
the number of pushes it takes to reach the determined heigth
the weigth of the boy
the heigth of the swing when it changes direction
Students in a science class are completing a lab about energy and speed. Students are rolling a marble down a ramp where it will collide with a plastic cup. Students must measure the distance the cup moves in centimeters. The students will conduct three trials for each high, medium,and low ramp using the exact same marble. Select the variable that the students change.
marble size
distance the cup travels
ramp heigth

Students must measure the distance the cup moves in centimeters. The students will conduct three trials for each high, medium, and low ramp using the exact same marble.
Select the explanation that correctly completes the group's statement about the outcome of the lab: "The cup that gained the most kinetic energy...
travels the greatest distance before stopping, because it had the greatest speed after the collision.
makes the loudest sound during the collision because it transfers the most kinetic energy to sound.
makes the quietest sound during the collision, because it transfers the most kinetic energy into sound.
travels the least distance before stopping because it transfers its kinetic energy the quickest to its surroundings.
Bases on the table, which ramp heogth results in the most kinetic energy of the ball at the bottom of the ramp?
The low ramp, because the marble has the lowest speed
The medium ramp, because the ball almost has an average of all the speeds
The highest ramp, because the ball has the highest speed.
