An object at rest will remain at rest unless an unbalanced force acts upon it.

• True

• False

What is Newton's first law of motion?

• Every action has an equal opposite reaction

• An object in motion stays in motion unless acted upon by an unbalanced force

• The force acting on an object is equal to the mass of an object times its acceleration

• Sandwich

The graphs show the motion of four different objects. Each object moved in a single direction during the time period shown in the graph. Which of the objects were acted on by unbalanced forces?

• objects B, C, and D only

• objects B and D only

• object B only

• object A only

How does Newton's Second Law apply when you push an empty shopping cart versus a full one?

• The empty cart requires more force to accelerate than the full one.

• The full cart accelerates more easily because it has more mass.

• The empty cart accelerates more easily because it has less mass.

• Newton's Second Law does not apply to shopping carts.

How does Newton's Second Law apply when Charlotte pushes an empty shopping cart versus when Ethan pushes a full one?

• The empty cart requires more force to accelerate than the full one.

• The full cart accelerates more easily because it has more mass.

• The empty cart accelerates more easily because it has less mass.

• Newton's Second Law does not apply to shopping carts.
