Two students are each holding a negatively charged balloon. The students firmly hold the balloons so that the balloons are close to each other but not touching. The students then release the balloons at the same time. Which statement BEST predicts how the balloons would move once they are released?

• The electrical force on the balloons will cause them to accelerate away from each other, increasing the distance between the balloons.

• The electrical force on the balloons will cause them to accelerate toward each other, increasing the distance between the balloons.

• The electrical force on the balloons will cause them to accelerate away from each other, decreasing the distance between the balloons.

• The electrical force on the balloons will cause them to accelerate toward each other, decreasing the distance between the balloons.

An athlete lifts two different exercise balls, a yoga ball and a medicine ball. The picture shows the yoga ball and the medicine ball. The medicine ball requires more force for the athlete to lift. Which claim is BEST supported by this data?

• The ball with the smaller volume has the weakest gravitational attraction with Earth.

• The ball with the larger volume has the strongest gravitational attraction with Earth.

• The ball with the larger mass has the greatest gravitational attraction with Earth.

• The ball with the smaller mass has the greatest gravitational attraction with Earth.

What is the difference between mass and weight?

• Mass refers to the amount of matter in an object, while weight is a measure of how much gravity is pulling on an object.

• Mass and weight are the same and can be used interchangeably.

• Weight is the amount of matter in an object, while mass is the force of gravity on it.

• Mass changes depending on location, but weight always stays the same.

On Earth, a bowling ball with a mass of 5 kilograms is dropped from a height of 10 meters. The ball hits the ground in 1.43 seconds. Which statement BEST describes the gravitational force between the ground and the ball?

• The ball exerts a force on the ground.

• The ground exerts a force on the ball.

• The ground and the ball repel each other with equal force.

• The ball and the ground attract each other with equal force.

When an object on Earth is thrown high into the air, it always returns to Earth's surface. Which statement is BEST supported by this phenomenon?

• The gravitational force depends on the direction in which the object is thrown.

• The gravitational force depends on the force with which the object is thrown.

• Gravitational interactions between two objects are attractive.

• Gravitational interactions between two objects are repulsive.

The data shown in the table represent net forces acting on four freely falling objects. Nash makes a claim that is supported by the data.

Use the drop-down menus to complete the claim.

The force of gravity causes freely falling objects to experience ​ (a)   acceleration. The data in the table support this claim because the ratio of ​ (b)   to ​ (c)   is ​ (d)   9.8 m/s².

• constant
• net force
• mass
• always
• never
• weight
• varying
• kilograms

Nash adds mass to the cart so that it has a total mass of 1.5 kg. He pulls the cart along the track with a constant force of 1.2 N. He records this information along with the average velocity of the cart as it passes each of the photogates.

Use the data table to determine the BEST explanation of why the average velocity of the cart increases from the first photogate to the second photogate?

• A. The mass of the cart causes it to accelerate.

• B. The net force on the cart causes it to accelerate.

• C. The mass of the cart causes it to keep a constant speed.

• D. The net force on the cart causes it to keep a constant speed.
