Gravitational Forces

What happens to the mass and weight of an object that is launched into space, where the pull of gravity is less?

• The mass decreases while the weight stays constant.

• The mass stays constant while the weight increases.

• The mass increases while the weight decreases.

• The mass stays constant while the weight decreases.

Change in v = 9.8 m/s 2 × t . The diagram shows a ball falling toward Earth in a vacuum. What is the velocity of the ball at 2 seconds?

• 9.8 m/s

• 19.6 m/s

• 29.4 m/s

• 39.2 m/s

• True

• False

If a tennis ball, a baseball, and a golf ball are dropped together from a high place, which ball will land first? (Assume there is no air resistance.)

Jennifer is explaining the difference between weight and mass to her little sister. In comparing the two, which of the following could Jennifer use to correctly describe the weight of an object?

• Weight is the same everywhere in space.

• Weight is how much matter is within an object.

• Weight is the amount of gravitational pull on an object.

• Weight is not impacted by the force of gravity.

What is the SI unit for measuring weight?

• Pound

• Ounce

• Kilgram

• Newton

The strength of the gravitational force between two objects depends on

• Mass and Matter

• Mass and Weight

• Mass and Distance

• Mass and Strength
