Gravitational Force Practice

When placed at equal distances apart, the greatest gravitational attraction will be between two

• skateboards

• bowling balls

• school buses

Which is needed to determine the amount of gravitational force between two objects?

• distance and mass

• weight and time

• area and weight

Why do we have a stronger gravitational attraction with Earth than the Sun?

• the sun has a larger mass

• the Earth has a larger mass

• we are closer to center of sun

• we are closer to center of Earth

An object with more mass will exert greater gravitational force than an object with lesser mass.

• True

• False

Which statement is true?

• All objects with mass exert a gravitational force.

• Only celestial objects exert a gravitational force.

• Gravity can both push and pull objects.

• Only Earth exerts a gravitational force.

Find the force due to gravity if the mass of the object is 2300 kg and the mass of the other object is 4000 kg. The distance between the two objects is 0.150 m.

• 4.09 x 10^-3 N

• 244 N

• 2.7 x 10^-2 N

• 6.14 x 10^-4 N

What would the gravitational force be between the Sun and Mars if they were 2.3 x 10¹¹ m apart? The masses for the Sun and Jupiter are 1.99 x 10³⁰ kg and 6.42 x 10²³ kg, respectively.

• F_g = 3.8 x 10¹⁵ N

• F_g = 2.8 x 10^-42 N

• F_g = 1.6 x 10²¹ N

• F_g = 4.6 x 10^-75 N

What is the proper setup of the gravitational force formula?

• F_g= Gm²/r

• F=ma

• F_g= Gr²/(m₁+m₂)

• F_g= G (m₁m₂)/r²

What effect does increasing the distance between the two objects do to the gravitational force?

• The distance between two objects has no effect on the gravitational force

• It increases

• It stays the same

• It decreases

• Universal gravitational constant

• Combined masses of the two objects

• Gravitational force

• Dielectric constant
