The illustration shows the forces in Newtons (N) acting on three different blocks. Which blocks will experience a change in motion, or acceleration?
Blocks 1 and 2
Blocks 2 and 3
Blocks 1 and 3
Blocks 1, 2, and 3
The illustration shows all the forces in Newtons (N) acting on a box. The sum of all the forces acting on the box results in a force acting on the box—
to the right with a strength of 11 Newtons
to the left with a strength of 7 Newtons
to the right with a strength of 25 Newtons
to the left with a strength of 6 Newtons
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. Which of the following changes to their setup would result in a larger force reading on the spring scale?
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. In order to vary the amount of force acting on the rocket, which of the following should the students change in each trial?
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?
