Multiple Choice

A box and forces are shown below. A box rests motionless on the ground. One student is pushing the box to the right with a force of 2 Newtons. The other student is pushing to the left with a force of 5 Newtons. In which direction and with what type of speed will the box move?

• It will move left at a constant speed

• It will move left at an increasing speed

• It will move right at a constant speed

• It will move right at an increasing speed

Multiple Choice

An image of a toy rocket and forces are shown here. Assuming the only two forces on the toy rocket are lift and gravity, which of the following combinations would result in the rocket moving upward?

• Lift= 5 Newtons / Gravity = 5 Newtons

• Lift = 3 Newtons / Gravity = 4 Newtons

• Lift = 5 Newtons / Gravity = 4 Newtons

• Lift = 4 Newtons / Gravity = 4 Newtons
