Students are investigating how mass affects the force needed to move an object. They attached a wooden block to a spring scale and placed a 10 g mass on top of the block and pulled it 50 cm across the table.What change(s) to their set-up would result in a larger force reading on the spring scale?
Changing the mass to a larger amount.
Changing the mass to a smaller amount
Pulling the block 10cm across the table
Using a different scale

inertia
reference frame
newton
