Gravitational Force | MCQs

Explanation

The earth moves around the sun.

زمین سورج کے گرد گھومتی ہے۔

"The" is used because it refers to a specific object, in this case, "the Earth."

It is a definite article used when speaking about something unique or specific.

Explanation

The gravitational force between two objects is independent of the medium between them.

Gravity acts through a vacuum just as it does through a medium like air, water, or solid objects.

The presence or absence of a medium does not affect the gravitational force between the objects.

Explanation

Gravitational force is always attractive, never repulsive.

According to Newton's law of universal gravitation, every point mass attracts every other point mass by a force acting along the line intersecting both points.

This means that gravity always pulls objects towards each other, never pushes them apart.

Explanation

According to Newton's law of universal gravitation, the force of gravity (F) is proportional to:

• The product of the two masses (m1 and m2): F ∝ m1 m2
• The inverse square of the distance (r) between the centers of the two objects: F ∝ 1/r^2

Explanation

The motion of a falling ball towards Earth is due to the gravitational force.

Gravitational force is the force that attracts the ball towards the Earth, causing it to accelerate downwards.
