Day 5 STAAR Glow Olympics-5.6D Checkpoint Quiz

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-

• how mass affects the force needed to move objects

• how force affects the mass of two objects

• how the force used to pull a dictionary affects the mass of a box of marbles

• how the mass of a box of marbles affects the mass of a 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.

Why is the depth of the dent different in each trial?

• The size of the ball changes.

• The material of the ball changes.

• The mass of the ball when it hits the clay changes.

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

Students conducted an investigation in which they measured the distance a toy car traveled after rolling down a ramp covered with sandpaper or wax paper.

Which of these questions can the students answer by analyzing the results of their investigation?

• How does changing the height of a ramp affect the distance a toy car rolls?

• How does changing the surface of a ramp affect the distance a toy car rolls?

• How does mass affect the distance a toy car moves after rolling down a ramp?

• How does the design of a toy car affect its movement after rolling down a ramp?

Some students attached a balloon to a straw and taped it to the top of a toy car. The students inflated the balloon and released the car. The car traveled 75 centimeters across the floor.

What should the students do to determine whether the force of the air from the balloon is enough to push the car 75 centimeters across the same floor in repeated trials?

• Test the car several times using identical balloons filled with different amounts of air.

• Test the car several times using different sized balloons filled with the same amount of air.

• Test the car several times using an identical balloon filled with the same amount of air.

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?

• How do blocks of different sizes react to force?

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

• How do blocks affect spring scales?

• How does the mass of a block change when it is pulled across a desk?
