The acceleration of a falling object does not depend on its mass. How does the mass of an object affect the force of gravity experienced by the object?

 

 

• The force of gravity is the same for all objects because acceleration is the same

• The force of gravity increases as mass increases.

• The force of gravity is the same for all objects because the force is determined by Earth’s mass.

• The force of gravity decreases as mass increases.

.   Which of the following terms describes an object's change in velocity over time?

 

• velocity

• Doppler effect

• position

• acceleration

Saturn is 9.5 astronomical units (AU) from the Sun, while Mars is only 1.5 AU from the Sun. Saturn is also larger than Mars. Based on this information, how does the average surface temperature on Mars compare to the average surface temperature of Saturn?

 

• Saturn is larger than Mars and absorbs more light, so it has a higher average surface temperature.

• Since both planets are more than 1 AU from the Sun, their average surface temperatures are equal

• Since Mars is closer to the Sun than Saturn, it has a higher average surface temperature.

• Even though Saturn is farther away, Saturn’s rings cause it to have a lower average surface temperature.
