High School Physical Science Review

Alexis and Candace were testing different surfaces to see which one had the least friction. They predicted that the marble, seen above, would travel FASTEST down the ramp when the surface covering had the LEAST friction. Alexis and Candace used rocks, plywood, and velcro to cover the ramp. They let the marble go, not pushing it, but letting gravity pull the marble to the bottom of the ramp. What were the controlled variables in the experiment?

• how fast the marble moved down the ramp

• ramp height, the marble, and using gravity

• the different types of ramp coverings

• pushing or not pushing the marble down the ramp

Solutions are mixtures that are very common in our daily lives. A solution is composed of a solute and solvent. A student conducted an investigation using 50 milliliters of distilled water and 5 grams of table salt. The water for each test was brought to a certain temperature before the salt was added. The data from the investigation is shown in the graph. Which conclusion best describes the data in the graph?

• The amount of solute in a solution determines the time needed for the solute to dissolve in the solvent.

• Increasing the amount of solvent increases the temperature of the solution.

• Increasing the temperature of the solute increases the amount of the solution.

• A decrease in the temperature of a solvent increases the time needed for a solute to dissolve in a solvent.

On Monday, Joey filled a glass with tap water. When he looked at the glass a few days later, some of the water had evaporated. Which of the following best describes what happened to the particles of water that evaporated?

• They are absorbed by the glass.

• They became larger in size.

• They spread out into the air.

• They passed through the glass into the air.

A student conducts a scientific investigation to determine which items have densities greater than water. The student knows that if an item has a density greater than water, it sinks. The student drops 4 different items into a beaker of water and records the outcomes in a table. What conclusion can the student make based on the data collected?

• The rock and the penny have greater densities than the water.

• All of the items have densities greater than water.

• The water is less dense than the birthday candle and the corn kernel.

• Water has a greater density than all the items.

• Anything that does not have mass or take up space.

• Anything that has mass but doesn't take up space.

• Anything that has mass and takes up space.

• Anything that does not have mass and takes up space.

A student places a ball on a level surface and performs a series of tests by applying varying amounts of force on the ball. The student measures the distances the ball travels in 30 seconds and records the data in the table shown. What can be inferred from the data?

• A minimum force of 1.2 N is required to move the ball.

• The larger the mass of the ball, the slower it moves with the application of the same force.

• The greater the force applied on the ball, the greater its change in speed.

• The ball travels a minimum distance of 1.0 m with the application of any force.

A student is pushing a toy car down a ramp. If the student places the toy car on the ramp again and increases the force used to push the toy car, what will happen?

• The kinetic energy will decrease, and the toy car will go faster.

• The kinetic energy will increase, and the toy car will go faster.

• The potential energy will increase, and the toy car will go slower.

• The potential energy will decrease, and the toy car will go slower.
