5.7 Forces Review

A student thinks that different-sized balloons make different forces as they let out air. Which experiment has a plan to BEST test this variable?

• Propel a toy car over different surfaces using different-sized balloons.

• Let the air out of different-sized balloons.

• Propel a toy car over the same surface using same-sized balloons.

• Propel a toy car over the same surface using different-sized balloons.

Which of the following best explains this picture?

• The person on the right has more force than the 3 on the left, causing a transfer of energy and the motion of the on the right.

• Energy is transferred from the person on the right to the 3 people on the left, causing the motion of both the person on the right and the 3 people on the left.

• The 3 people on the left have more force than the person on the right, causing a transfer of energy and the motion of the person on the right.

• Balanced forces cause the motion and energy of the person on the right to be the same as the motion and energy of the 3 people on the left.

Which of the following best describes this picture?

• The forces are equal, meaning there is no overall movement to the left or right.

• The forces are unbalanced causing a transfer of energy and motion to the right.

• The forces are unequal causing the team on the left to move forward.

• It is impossible to tell if the forces are equal or unequal in the picture.

• the same mass, different forces

• the same mass, the same force

• different masses, different forces

• different masses, the same force
