Gravity and Inertia

Front

What is inertia?

Back

Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force.

Front

What does gravity do in the solar system?

Back

Gravity is the force that attracts two bodies towards each other, keeping planets and other celestial bodies in orbit.

Front

What is the relationship between distance and gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

Why does the Moon orbit Earth instead of the Sun?

Back

The Moon orbits Earth because it is closer to Earth than to the Sun, resulting in a stronger gravitational pull from Earth.

Front

What is the role of gravity in keeping planets in orbit?

Back

Gravity provides the necessary centripetal force that keeps planets in their elliptical orbits around the Sun.

Front

What is the difference between mass and weight?

Back

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

Front

How does mass affect gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What is the formula for gravitational force?

Back

The gravitational force (F) between two objects is given by F = G * (m1 * m2) / r^2, where 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 a gravitational field?

Back

A gravitational field is a region of space around a mass where another mass experiences a force of attraction.

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the calculation of gravitational force between two masses.
