5.6D Science STAAR (Force & Motion)

Front

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk. Then the student pulls the block the same distance across surfaces of carpet, sandpaper, and glass. Which question is this investigation most likely designed to answer?

Back

How do different surfaces affect the amount of force needed to move a block?

Front

A student designs an experiment to test the force of a spring using a spring launcher and four spheres with the same diameter but with different masses. What other piece of equipment would be most useful for this experiment?

Back

A meterstick to measure the height each sphere reaches after the sphere is launched.

Front

What should the student do to improve the experiment testing the effects of the width of a piece of elastic on its ability to stretch? Options: Use blocks of equal mass on the four pieces of elastic, Use blocks with enough mass to cause the four pieces of elastic to break, Use more than four pieces of elastic and four blocks, Use four pieces of elastic with different lengths but the same width

Back

Use blocks of equal mass on the four pieces of elastic

Front

Why is the depth of the dent different when a heavy ball is dropped onto identical blocks of soft clay from different heights?

Back

The force of the ball when it hits the clay changes.

Front

The diagrams show two trials of an experiment in which a spring scale was used to measure force. This experiment can be used to determine---

Back

how mass affects the force needed to move objects

Front

Students design an experiment to determine how much force is needed to move blocks of wood of different masses slowly across a lab table. Which procedure should students include in their design?

Back

Conduct five trials, pulling each block of wood in the same way for each trial.
