Gravity and Inertia

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

How does the mass of an object affect its gravitational pull?

Back

The gravitational pull of an object increases with its mass; more massive objects exert a stronger gravitational force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion, meaning it will remain at rest or in uniform motion unless acted upon by a force.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which is equal to the mass of the object multiplied by the acceleration due to gravity (Weight = mass × gravity).

Front

What factors affect the gravitational force between two objects?

Back

The gravitational force between two objects is affected by their masses and the distance between them.

Front

What happens to weight when gravitational force changes?

Back

Weight changes with variations in gravitational force; for example, an object weighs less on the Moon than on Earth due to the Moon's weaker gravity.

Front

What is the role of the Sun's gravitational force in the solar system?

Back

The Sun's gravitational force holds the Earth and other planets in orbit around it.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases; it is inversely proportional to the square of the distance.

Front

What is the formula for calculating gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers.

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object and does not change regardless of location, while weight is the force of gravity acting on that mass and can change with the strength of the gravitational field.
