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 a block?
How do blocks affect spring scales?
How does the mass of a block change when it is pulled across a desk?
A student designs an experiment to test the force of 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?
A graduated cylinder to measure a volume of each sphere before the sphere is launched.
A beaker to collect the spheres after they have been launched
A stopwatch to measure how long it takes to load each sphere on the spring
A meter stick to measure the height each sphere reaches after the sphere is launched
tool used to measure force in Newtons (N)
spring scale
friction
magnetism
gravity
These are the variables that should stay the same. They do not get any changes in order to make for a fair test.
