Gravity and Orbits

Front

What is the definition of mass in the context of physics?

Back

Mass is a measure of the amount of matter in an object, which remains constant regardless of its location in the universe.

Front

What is an orbit?

Back

An orbit is the curved path of an object around a point or object in space, typically due to gravitational forces.

Front

How does gravitational attraction vary between two models?

Back

Gravitational attraction depends on the mass of the objects and the distance between them; Model A has greater gravitational attraction if it has more mass or is closer together.

Front

Which planet takes the least amount of time to revolve around the Sun?

Back

Mercury takes the least amount of time to revolve around the Sun due to its proximity to the Sun.

Front

What is the relationship between a planet's distance from the Sun and its orbital speed?

Back

The closer a planet is to the Sun, the faster it orbits due to stronger gravitational pull.

Front

What is the formula for gravitational force between two objects?

Back

The gravitational force (F) is calculated using the formula 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 the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a key value in the equation of gravitational force, determining the strength of the gravitational attraction between two masses.

Front

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

Back

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

Front

What is the effect of distance on 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 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.
