What other piece of equipment would be most useful to test the force of a spring? The test is using the spring launcher and 4 spheres with the same diameter but with different masses.
METER STICK--to measure the height each sphere reaches after the sphere is launched
Which sphere will launch the farthest and why?
The 10 g sphere because it is the lightest
What needs to happen at Step 3 to complete the experiment about the size and formation of moon craters?
Drop marbles of different masses from the same height into the pan of flour
What should students do to determine whether the force of the air from the balloon is enough to push the car 15 centimeters across the same surface in repeated trials?
Test the car several times using an identical balloon filled with the same amount of air
How can you improve this experiment that is testing the effect of the width of a piece of elastic on the elastic’s ability to stretch?
Use blocks of equal mass on the four pieces of elastic.
Why is the depth of the dent different each time that ball is dropped onto identical blocks of soft clay?
1. The height of the drop is different 2. The force of the ball when it hits the clay changes
Why does this experiment need to be repeated multiple times?
To get the most accurate results
What question is this investigation most likely designed to answer if the same block of wood and spring scale is pulled horizontally across carpet, wood, sandpaper, and glass?
How do different surfaces affect the amount of force needed to move a block?
Why are there different surfaces for the cars to roll down in the picture?
To test how different surfaces affect the speed of an object
