"Where accuracy builds trust, much like the fundamental forces of nature."

Which of the following best describes the concept of weightlessness experienced by astronauts in space?

Explanation: Weightlessness experienced by astronauts in space is due to free-fall in a gravitational field, where both the spacecraft and the astronauts are accelerating towards the Earth at the same rate, creating a sensation of zero gravity.

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

Explanation: According to Newton's law of gravitation, if the mass of one object is doubled, the gravitational force between the two objects also doubles, as force is directly proportional to the product of their masses.

What happens to the gravitational potential energy of an object as it is raised to a greater height above the Earth's surface?

Explanation: Gravitational potential energy increases as an object is raised to a greater height because it is given more potential to do work due to gravity.

Which of the following best describes gravitational potential energy?

Explanation: Gravitational potential energy is the energy stored in an object due to its position in a gravitational field, typically calculated as U=mghU = mgh.

How does the gravitational force between two objects change if the distance between them is doubled?

Explanation: According to the inverse-square law, if the distance between two objects is doubled, the gravitational force between them decreases by a factor of 4.

What is the weight of an object?

Explanation: The weight of an object is the force exerted by gravity on the object, which is calculated as W=mgW = mg, where mm is the mass and gg is the acceleration due to gravity.

Which of the following describes the motion of planets around the Sun according to Newton's law of gravitation?

Explanation: According to Newton's law of gravitation, the motion of planets around the Sun is elliptical, with the Sun at one of the foci of the ellipse.

Which phenomenon explains why objects fall towards the Earth?

Explanation: Objects fall towards the Earth due to gravitational attraction, which pulls objects towards the center of the Earth.Explanation: Objects fall towards the Earth due to gravitational attraction, which pulls objects towards the center of the Earth.

Which scientist formulated the law of universal gravitation?

Explanation: Sir Isaac Newton formulated the law of universal gravitation, which states that every particle attracts every other particle with a force proportional to their masses and inversely proportional to the square of the distance between them.v

What is the force of attraction between any two objects in the universe called?

Explanation: Gravitational force is the attractive force that acts between any two objects in the universe due to their masses.
