Luis rubbed a balloon on his hair and held the balloon next to a faucet trickling water. He observed that as the balloon was placed close to the water, the stream of water appeared to “bend” to move out of the way. Which of the following forces is responsible for the stream of water moving away from the balloon?

Gravity

Magnetism

Friction

Electric

It will pull the boards toward each other

It will hold the boards steady in one place

It will spin the boards in opposite directions

Imagine two planets, Planet A and Planet B, in a distant galaxy. Both planets have the same size, but Planet A has more mass than Planet B. Suppose two identical alien space vehicles land on each planet. Which of the following statements is true?

The weight of the space vehicle is greater on Planet A, but the vehicle’s masses are the same on both planets

The mass of the space vehicle is greater on Planet A, but the vehicle’s weights are the same on both planets

Both the mass and weight of the space vehicle are greater on Planet A

Both the mass and weight of the space vehicle are the same on both planets

A ball rolls down from the top of a grassy hill, reaches the bottom of the hill, continues to roll, and then starts to slow down and comes to a stop. What forces caused this ball's motion?

Frictional force caused the ball to roll down the hill, but air resistance caused the ball to slow down and stop.

Magnetic force caused the ball to roll down the hill, but gravity caused the ball to slow down and stop.

The force of the hill caused the ball to roll down it, but gravity caused the ball to slow down and stop

Gravity caused the ball to roll down the hill, but frictional force caused the ball to slow down and stop.

The diagram below shows forces acting on a model airplane. Both its speed and height above the ground are constant.

The lift is equal to the drag.

The lift is less than the weight.

The thrust is equal to the weight.

The thrust is greater than the drag

A scientist created the graph below of the motion of three objects. Which of the following is correct about the motion of the objects?

Object Q is not moving at all

Object S is traveling at a faster speed than Object R

Object R is increasing in speed by 2 m/s

Object R is traveling at a slower speed than Object S

Electromagnetic radiation is energy that travels in waves. Some examples of electromagnetic radiation are visible light, radio waves, and x-rays. Which statement is true for all forms of electromagnetic radiation?

All forms of electromagnetic radiation travel at the same speed in a vacuum.

All forms of electromagnetic radiation have the same frequency

All forms of electromagnetic radiation have the same wavelength

All forms of electromagnetic radiation have the same amount of energy in a vacuum

Which of the following colors of the Visible Light Spectrum has the lowest amount of energy?

Yellow

Green

Blue

Orange

A light wave from the sun shines through the atmosphere, into the window of a house, and through a plastic fish tank. In which of the following mediums would the light waves travel the fastest?

The air in the atmosphere

The glass in the window

The water in the fish tank

The plastic fish tank

11.

While watching a popular space-based science fiction movie, space vehicles loudly shoot each other with lasers and explode with a booming sound. Students of science know that sound does not travel through space and these movie scenes showing space sounds are factually incorrect. Why are there no sounds in space?

Sound waves travel as transverse waves

Sound waves require a medium

Sound waves can only travel through air particles

Sound waves have high frequencies

12.

Emma constructed a simple motor. When connected correctly, the coil of copper wire spins. Which of the following best describes the energy transformation that takes place between the paper clips and the spinning coil?

Chemical energy transforms into electrical energy

Mechanical energy transforms into electrical energy

Electrical energy transforms into mechanical energy

Mechanical energy transforms into chemical energy

13.

A television is a device that converts electrical energy into light and sound energy. Not all the energy that enters a television is converted into light and sound, however. What happens to the energy that enters a television but is not converted into light or sound?

The energy returns to the electrical socket.

The energy is stored in the wires in the television

The energy is converted to heat

The energy is destroyed in the conversion process

14.

Ms. Simpson's science students were observing a demonstration with Newton's cradle, as shown in the diagram below. They noticed that when the ball was raised and released on the left side, it hit the stationary balls, and its kinetic energy was transferred all the way to the last ball on the right, causing it to be propelled up. This action continued for a while, but as time went on, the balls did not go as high and eventually stopped. Why did the balls stop moving?

The combined mass of the balls could not be overcome by the force of one moving ball.

Due to the force of gravity pulling the balls down, energy was continually lost to the surrounding environment

Due to air resistance and friction between the string and the frame, some of the energy was transferred to the surroundings as heat.

The three middle balls blocked the energy from getting to the outside balls, so they could not rise as much

15.

A group of students are eating in the cafeteria. As they eat, the students break down the molecules in the food, which releases energy. Which form of energy is stored in the food?

Chemical energy

Elastic energy

Nuclear energy

Thermal energy

16.

Mary throws a tennis ball into the air. It rises, stops momentarily when it reaches its greatest height, and then falls back to the ground. At what point does kinetic energy converted to potential energy?

When the tennis ball is rising

When the tennis ball is falling

Just after the tennis ball hits the ground

While the tennis ball is at the highest point

17.

What happens when a solid melts?

Its molecules move farther apart

Its molecules move closer together

The speed of its molecules decreases

The temperature decreases although heat is added

18.

Some ice cubes are added to a pot of boiling water. After a few moments, the water stops boiling. Which of the following explains why the water stopped boiling?

Heat energy from the water melted the ice

Particles from the boiling water moved into the ice and melted the ice

Cold energy from the ice transferred into the water, lowering the temperature of the water

19.

Roberto is a musician playing in a band. At the end of a song, he plucks a single guitar string. The string moves rapidly back and forth. Which of these statements explains what happens to the kinetic energy of the moving string?

The kinetic energy is changed into potential energy and stored.

The kinetic energy is converted to sound energy and thermal energy

The kinetic energy is slowly destroyed until no energy remains

Some of the energy is converted to sound energy, but the rest is destroyed

20.

In a lab, a scientist has a beaker of pure water and a battery at the bottom. When he places a lightbulb in the water, the light bulb does nothing. He then adds salt to the water, and places the lightbulb in the water with salt in it, and the lightbulb lights up. What physical property was produced in the water when salt was added to the water?

Solubility

Flammability

Malleability

Conductivity

21.

The table shows the properties of four unknown liquids. Each sample is in its own beaker. A student adds equal amounts of substance K to each beaker. If substance K has a known density of 6.4 g/mL, in which liquids would K sink?

W and X

X and Z

W and Y

Y and Z

22.

A student determines the volume, density, and boiling point of three colorless liquids and lists them in the table below. Could any of the liquids be made of the same substance? Why?

. Liquids 1 and 2 could be the same substance because they have the same density

Liquids 1 and 3 could be the same substance because they have the same volume

Liquids 1, 2, and 3 could be the same substance because they are all clear liquids

None of the liquids could be the same substance because they have different combinations of density, and boiling points

23.
