Universal Gravitation Review

What is the relationship between mass and gravitational force?

• Gravitational force is inversely proportional to the product of the masses.

• Gravitational force is directly proportional to the product of the masses; as either mass increases, the gravitational force increases.

• Gravitational force is independent of the masses involved.

• Gravitational force decreases as the distance between the masses increases.

What does the gravitational constant (G) represent?

• A proportionality factor used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

• The force of gravity between two objects with mass.

• The acceleration due to gravity on the surface of the Earth.

• A measure of the strength of the electromagnetic force.

What is the effect of a large distance on gravitational attraction?

• A large distance results in a stronger gravitational attraction due to the inverse square relationship.

• A large distance has no effect on gravitational attraction.

• A large distance results in a weaker gravitational attraction due to the inverse square relationship.

• A large distance increases gravitational attraction exponentially.

How does gravitational force affect satellite motion?

• Gravitational force provides the necessary centripetal force for satellites to maintain their orbits around larger bodies.

• Gravitational force causes satellites to move in a straight line away from the planet.

• Gravitational force has no effect on satellite motion; it only affects objects on the surface of the planet.

• Gravitational force pulls satellites directly towards the planet, causing them to crash.

What is the relationship between distance and gravitational force?

• Gravitational force is directly proportional to the distance.

• Gravitational force is inversely proportional to the square of the distance.

• Gravitational force is unaffected by distance.

• Gravitational force increases with distance.

How does the gravitational force between two objects change if both masses are doubled?

• The gravitational force will remain the same.

• The gravitational force will increase by a factor of 2.

• The gravitational force will increase by a factor of 3.

• The gravitational force will increase by a factor of 4, since F is proportional to the product of the masses.

What is the significance of the center of mass in gravitational calculations?

• It is the point where the mass of an object is concentrated, and gravitational force calculations are based on the distance between the centers of mass.

• It represents the average position of all the mass in an object, which is irrelevant in gravitational calculations.

• It is the point where gravitational forces are equal, making it crucial for balance in structures.

• It indicates the maximum gravitational pull an object can exert on another object.

What is the role of gravitational force in the formation of celestial bodies?

• Gravitational force causes matter to clump together, leading to the formation of stars, planets, and other celestial bodies.

• Gravitational force repels matter, preventing the formation of celestial bodies.

• Gravitational force has no effect on the formation of celestial bodies.

• Gravitational force only affects the orbits of existing celestial bodies.

What is the concept of gravitational equilibrium?

• Gravitational equilibrium occurs when the gravitational forces acting on an object are balanced, resulting in no net force.

• Gravitational equilibrium is the state where an object is in free fall due to gravity without any other forces acting on it.

• Gravitational equilibrium refers to the condition when an object is at rest on the surface of a planet, unaffected by gravity.

• Gravitational equilibrium is achieved when an object is moving at a constant speed in a straight line.

What is the formula for gravitational force between two masses?

• F = G * (m1 * m2) / r^2

• F = m1 * m2 * r^2 / G

• F = G * (m1 + m2) / r

• F = G * (m1 - m2) / r^2
