Newton's Law of Universal Gravitation

What is the formula for gravitational force?

• F = G * (m1 * m2) / r^2

• F = m * a

• F = G * (m1 + m2) / r^2

• F = G * (m1 * m2) * r^2

What is weight in terms of gravitational force?

• Weight is the mass of an object multiplied by the acceleration due to gravity (W = m * g).

• Weight is the total mass of an object regardless of gravity.

• Weight is the force exerted by an object in motion.

• Weight is the measure of an object's resistance to acceleration.

What is the difference between mass and weight?

• Mass is the force exerted by gravity on an object, while weight is the amount of matter in that object.

• Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

• Mass and weight are the same; they both refer to the amount of matter in an object.

• Weight is the measure of an object's volume, while mass is the measure of its density.

What is the acceleration due to gravity on Earth?

• Approximately 9.81 m/s².

• Approximately 8.00 m/s².

• Approximately 10.5 m/s².

• Approximately 9.00 m/s².

What is Newton's Law of Universal Gravitation?

• It states that every point mass attracts every other point mass by a force pointing along the line intersecting both points.

• It describes the motion of planets around the sun due to magnetic forces.

• It explains the relationship between mass and energy in a closed system.

• It states that gravity is a force that only affects large celestial bodies.
