Which of the following statements about speed and velocity is correct?
Velocity only describes an object’s rate of motion.
Speed describes how an object is changing its velocity.
Speed and velocity both describe how an object is speeding up.
Only velocity includes the direction an object is traveling.
Which of the following objects is not changing its velocity?
golf ball rolling down a ramp
skateboard rolling up a hill
cue ball rolling forward at a constant speed
marble going around the curve in a track
Acceleration describes how an object’s velocity is changing. Which of the following scenarios provides the best example of an accelerating object?
A car driving at a constant speed
A book sitting on top of a high shelf
A toy train traveling in a circle
A toy boat floating in a bathtub
The distance an object travels in a specific amount of time.
Speed
Velocity
Acceleration

The circuit has three lightbulbs and a bell. Which procedure will result in the green bulb operating, the bell producing a sound, and only one blue lightbulb operating?
Close Switch 1 and leave Switches 2 and 3 open
Close Switches 2 and 3, and leave Switch 1 open
Close Switches 1, 2, and 3
Leave Switches 1, 2, and 3 open
The picture below shows a spoon in a glass of water. Why does the spoon appear bent?
the light waves are refracted as they change speed when they pass from the water to the air
the light waves are reflected as they change speed when they pass from the water to the air
the light waves are absorbed when they pass from the water to the air
the light waves bounce off of the water
Students constructed a circuit using different-colored lightbulbs. What will happen if Switch 2 is closed and the other switches are left open?
Only the white bulb will operate.
None of the bulbs will operate.
Only the white and blue bulbs will operate
Only the red and yellow bulbs will operate.
Which of these BEST describes the change in salt grains as they dissolve in water?
The grains change their chemicals until they become water.
The grains get higher in temperature until they melt into a liquid.
The grains get smaller in size until they can no longer be seen.
the grains are washed clean until they are perfectly clear.
Which statement about gases is NOT true?
Gas particles move freely.
Gases have definite shape.
Gases fill all available space in a container.
Water evaporates into gas.
What happens when a small amount of salt, seaweed, and sand mixes with water?
the salt clumps into larger pieces
the sand and seaweed mix with the salt, and you can still see all the solids
the sand breaks into pieces too small to be seen
the seaweed floats to the top
Circuit A is constructed using a 6-volt battery, copper wires, and a bell. Circuit B is constructed using a 9-volt battery, string, and a bell. Circuit A produced a sound, but Circuit B did not produce a sound. Which of the following most likely explains why circuit B did not produce a sound?
The electricity traveled in a complete path.
There was not a switch in the circuit.
The bell was designed to produce a small amount of sound energy.
the string is a poor conductor of electricity.
Some students were studying different types of mixtures. They stirred together one cup of oil and one cup of water in a large glass beaker. They observed that the water settled to the bottom and the oil floated to the top. Which of the following does this investigation demonstrate?
The oil completely dissolved in the water.
The oil maintained it physical properties.
The oil was more dense than the water.
The oil melted in the water.

Container 1
Container 2
Container 3
Container 4
