Properties of Matter

The diagram (picture) shows two trials of an experiment in which a spring scale was used to measure force. Which statement is a reasonable conclusion?

• It takes more force to pull a load with more mass.

• It takes less force to move a load with more mass.

• The force needed to move a heavier load is the same as the force needed to move a lighter load.

• The mass of the marbles changes the mass of the dictionary.

Students drop the same heavy ball onto identical blocks of soft clay from different heights. For each height they measure the depth of the dent the ball makes in the clay. Which question is the student most likely trying to answer with this investigation?

• Does the height of the release affect the force of the impact?

• Does the mass of the ball affect the force of the impact?

• How does the mass of the ball change?

• How does the mass of the ball increase?

A student designs an experiment to test the effect (result) of the width of a piece of elastic on the elastic's ability to stretch. The student uses four different pieces of elastic with different widths but the same length when not being stretched. The student then attaches blocks with different masses to the pieces of elastic. The results of the student's experiment are shown in the picture.

What should the student do to improve this experiment?

• Use blocks of equal mass on each of the four pieces of elastic.

• Use blocks with enough mass to cause each of the four pieces of elastic to break.

• Use more than four pieces of elastic and more than four blocks.

• Use four pieces of elastic each with different lengths but the same width.

A student designs an experiment to test the force of a spring launcher and four spheres with the same diameter (same size) but with different masses.

Which question is the student most likely trying to answer with this investigation?

• How does the mass of an object affect the height reached by that object?

• How do different surfaces affect the height reached by an object?

• How can you reduce the mass of each object?

• Which surface creates the most friction?

How can the student improve the investigation?

• Use repeated trials for each surface.

• Use different blocks for each of the different surfaces.

• Use more than 3 surfaces.

• Use a block with more mass.

A student designs an experiment to test the force of a spring launcher and four spheres with the same diameter (same size) but with different masses.

What other piece of equipment would be most useful for this experiment?

• A graduated cylinder to measure the volume of each sphere before it is launched.

• A beaker to collect the spheres after they are launched.

• A stopwatch to measure how long it takes to load each sphere on the spring.

• A meterstick or measuring tape to measure the height each sphere reaches after the sphere is launched.
