The letters N and S show the magnetic poles.
Jacob puts two magnetic toy trains very close to each other on a track. What will happen next?
The trains will repel and move away from each other.
The trains will attract and move away from each other.
The trains will attract and move towards each other.
The trains will not move.
A cyclist is traveling up a mountain. When the rider reaches the top of the mountain, she stops to rest. Then she travels down the mountain. The diagram shows the cyclist in the three different positions.
Which of these correctly describes the potential energy and the kinetic energy of the cyclist?
The cyclist reaches the bottom of the hill, her kinetic energy and her potential energy decrease
When the cyclist is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.
As the cyclist moves up the hill, her kinetic energy increases, and her potential energy decreases.
When the cyclist goes down the hill, her potential energy increases, and her kinetic energy decreases
As the shuttle descended, it slowed until a parachute could be opened for a landing at sea. Which of the following explains how the shuttle slowed down to land?
The parachute created an upward force to resist the downward force of gravity.
The parachute created an upward force to resist the upward force of gravity.
The parachute created a downward force to resist the upward force of gravity.
The parachute created a downward force to resist the downward force of gravity.
A car is traveling down the road. Suddenly, its speed increases. What can you say about the kinetic energy of the car?
The kinetic energy decreases as it is converted into speed.
There is no way to know what happens to the kinetic energy.
The kinetic energy increases as its speed increases.
The kinetic energy remains the same because speed and kinetic energy are not related.
Kelsey sets identical magnetic carts on two tracks. At the end of each track is a large magnet that cannot move. Kelsey can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
Move track 1 car one space to the right
Both cars will result in a change in PE
Move track 2 car one space to the left
Move track 2 car one space to the right
Boron is a metalloid. Which of the following statements best describe a metalloid?
Boron is like a nonmetal and is very brittle
Boron is like a metal and a gas at room temperature
Boron is like a nonmetal and it is a good conductor
Boron is like a nonmetal because it is malleable
Katy gathered a sample of water from a lake to examine under a microscope. Which statement indicates that the sample of water contain living organisms?
molecules were seen
small cells were seen
the sample has a brown color
the sample produces gas
Objects that have smaller volume, have a greater density.
True
False
Which of the following is a biotic factor interacting with a dog?
The dog using grass to scratch its back
The dog playing with a rock.
The dog playing with a chew toy.
The dog laying on itsdog bed.
What happens to the potential energy if you move two repelling magnets against each other?
PE decreases since it is moving the same direction
PE deceases since it is moving with the magnetic field
PE does not change
PE increases since it is moving against the magnetic field
Which ramp requires less force if you are pushing a wheel barrel up the ramp?
shorter ramp: decrease ramp incline and less force is needed
longer ramp: decrease ramp incline and less force is needed
longer ramp: increase ramp incline and less force is needed
shorter ramp: increase ramp incline and less force is needed
The table below shows two experiments. Which statement is true about the experiments in the table?
Both experiments show chemical changes
Both experiments show physical changes
Experiment 1 shows a chemical change and Experiment 2 shows a physical change
Experiment 1 shows a physical change and Experiment 2 shows a chemical change
What is happening in the magnets in set 1 and set 2?
Set 1 attracts and Set 2 repels
Both sets repel
Set 1 repels and Set 2 attracts
Both sets attracts
