Understanding Universal Gravitation

What is the formula for calculating gravitational force?

• F = m1 * m2 / r

• F = G * (m1 * m2) / r^2

• F = G * (m1 + m2) * r

• F = G * m1 * m2 * r^2

If the mass of two objects is doubled, how does the gravitational force change?

• The gravitational force increases by a factor of two.

• The gravitational force remains the same.

• The gravitational force increases by a factor of four.

• The gravitational force decreases by half.

Calculate the gravitational force between two 5 kg masses that are 2 meters apart.

• 9.8 N

• 2.5 N

• 4.17125e-10 N

• 1.67e-10 N

What happens to the gravitational force if the distance between two objects is halved?

• The gravitational force increases by a factor of 8.

• The gravitational force increases by a factor of 4.

• The gravitational force remains the same.

• The gravitational force decreases by a factor of 2.

If the mass of one object is 10 kg and the other is 20 kg, what is the gravitational force between them at a distance of 1 meter?

• 1.0 N

• 1.3348 × 10^-9 N

• 6.674 × 10^-11 N

• 2.0 × 10^-9 N

How does the gravitational force between two objects change if one object's mass is tripled?

• The gravitational force remains unchanged.

• The gravitational force increases by a factor of three.

• The gravitational force decreases by a factor of three.

• The gravitational force increases by a factor of six.

If the gravitational force between two objects is 10 N and the distance is increased to 4 meters, what will the new force be?

• 5 N

• 1 N

• 20 N

• 2.5 N

What is the effect of increasing the distance on gravitational force?

• Gravitational force is only affected by mass, not distance.

• Distance has no effect on gravitational force.

• Increasing the distance decreases the gravitational force.

• Increasing the distance increases the gravitational force.

If the gravitational force is 15 N and one mass is 3 kg, what is the mass of the other object if they are 1 meter apart?

• 7.5e+10 kg

• 5 kg

• 10 N

• 1.5e+10 kg

Explain why gravitational force is always attractive.

• Gravitational force is influenced by electromagnetic interactions.

• Gravitational force is only attractive at short distances.

• Gravitational force is always attractive due to the nature of mass and spacetime curvature.

• Gravitational force can repel objects under certain conditions.
