A student rolls a ball down the ramp shown in the picture The ramp is supported by four stacked books.
The student removes two books from the stack supporting the ramp and rolls the ball down the ramp again. Which of the following statements best describes how the ball’s motion is different after the books are removed?
The ball accelerates more quickly down the ramp.
The ball has a higher speed at the top of the ramp.
The ball takes more time to reach the bottom of the ramp.
The ball has a higher average speed when it rolls off the ramp.

The diagram below shows what occurred when a can of diet soda and a can of regular soda were dropped into a container of water. The can of regular soda sank to the bottom of the container, but the can of diet soda floated. Which of the following statements best explains this observation?
The can of regular soda is less dense than the can of diet soda.
The can of regular soda is more dense than the can of diet soda.
The can of regular soda has a larger volume than the can of diet soda.
The can of regular soda has a smaller volume than the can of diet soda.
The table shows the masses and volumes of four cubes made of different materials.
Which cube has the greatest density?
Cube 1
Cube 2

Four objects have different forces applied to them. All of the horizontal forces acting on each object are shown in the diagrams below. Which diagram shows that the speed is not changing?
Which of the following models has the greatest attractive electric force between the charged particles?
Which of the following examples best describes one type of energy changing into another?
A magnet sticking to a refrigerator
Sound traveling through a solid wall
An electric heater warming up a cold room
Light rays bending as they pass through glass
In a science investigation, a student holds a vibrating tuning fork near a piece of cork, as shown in the picture.
The student observes that the cork moves. Which of the following conclusions can be made from this investigation?
Sound is a form of energy
Sound does not travel in air.
Sound cannot travel through the cork.
Sound is transformed into magnetic energy.
Methane and propane are two compounds that are composed only of carbon and hydrogen atoms. The table below shows some of the properties of these two compounds.
Which of the following conclusions is best supported by the information in the table?
When two elements combine, the mass of each element changes.
When two compounds are mixed, the state of matter of the mixture changes.
Two elements can combine to produce different substances with different properties.
Two compounds can be mixed together to produce different materials with different properties
A teacher performs an investigation by heating a 5.4 g piece of aluminum and placing it into a beaker of water. The table shows the temperatures before and after the aluminum was placed in the water.
The teacher repeats the investigation using a larger, 20 g piece of the aluminum heated to 100°C. Which of the following best explains what will happen to the final temperature of both the water and the 20 g piece of aluminum?
The temperature will be 28°C because both pieces of aluminum transfer heat energy at the same rate.
The temperature will be 28°C because both pieces of aluminum are heated to the same initial temperature.
The temperature will be lower than 28°C because the smaller piece of aluminum transfers heat energy more quickly than the larger piece of aluminum.
The temperature will be higher than 28°C because the larger piece of aluminum transfers more heat energy to the water than the small piece of aluminum.
