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.

• Sliding the block 60 cm

• Attaching a larger spring scale

• Using a 20 g mass

• Using a circular piece of wood

Students are using an air rocket to investigate the relationship between force and an object's motion. Students pump air into the rocket, then release the rocket, and the compressed air pushes the rocket upward.

• The length of the hose attached to the pump

• The distance traveled by the rocket

• The amount of air pumped into the rocket

• The height of the rocket from fins to cone

Which of the following graphs shows how the mass of an object affects the amount of force needed to move it?

• [Graph A: Horizontal line showing no change in force with increasing mass]

• [Graph B: Diagonal line showing increasing force with increasing mass]

• [Graph C: Parabolic curve showing force increasing and then decreasing with increasing mass]

• [Graph D: Diagonal line showing decreasing force with increasing mass]
