Samuel kicks a soccer ball across a grassy field and it eventually comes to a stop. If Newton’s law of inertia is true, why did the ball stop?

Friction with the grass applies a net force on the ball causing it to decrease its speed.

Newton’s law only applies to objects at rest.

The mass of the ball is not great enough to have inertia.

Gravity slowed the ball until it came to a stop.

an old star on the main sequence

During a football game, a quarterback passes a ball through the air. What will happen to the ball as it is traveling in the air?

It’s speed will decrease due to air friction.

It’s speed will decrease due to its mass.

It’s speed will increase due to the quarterback’s arm.

It will travel at a constant speed the entire time.

The polar bear depends on sea ice in order to hunt for seals. If arctic temperatures increase, what is the long- term outlook for polar bears?

polar bear population will gradually decrease

polar bear population will gradually increase

polar bear population will remain unchanged
