Using the graph on the left, which object was pushed by a greater force (both have the same mass)? How do you know?

• Object A; it has a steeper slope

• Object B; it has a steeper slope

• Object A; it has a flatter slope

• Object B; it has a flatter slope

What evidence did you collect that supports the idea that force and acceleration are directly proportional?

• When we changed the strength of the fan force pushing two identical carts, the cart

  with the strongest fan force increased its velocity at a greater rate.

• When we changed the strength of the fan force pushing two identical carts, the cart

  with the strongest fan force decreased its velocity at a greater rate

• When we changed the strength of the fan force pushing two identical carts, the cart

  with the smallest fan force increased its velocity at a greater rate

• When we changed the strength of the fan force pushing two identical carts, the cart

  with the strongest fan force increased its velocity at a lower rate

What is an example of an inversely proportional relationship in your life?

• The more you study, the lower your grades

• The more you exercise, the more energy you have

• The more you eat, the more weight you gain

• The more you sleep, the better you feel

Summarize Newton's Second Law in your own words.

• Force is equal to mass times acceleration

• Force is equal to velocity times mass

• Acceleration is equal to force times mass

• Acceleration is equal to velocity times force

Why is it harder to stop a semi-truck than it is to stop a small car if they are both traveling at the same speed?

• The semi-truck has more force

• The semi-truck has more acceleration

• The semi-truck has more mass

• The semi-truck has more velocity

Describe how you are able to tell if a force is acting on an object by looking at the velocity-time graph.

• The graph shows a steep slope and the velocity is changing

• The graph shows a flat slope and the velocity is not changing
