Gravity & Orbits

Front

What happens to the force of gravity as the distance between two objects increases?

Back

The force of gravity decreases.

Front

What prevents planets from falling into the Sun?

Back

Inertia/Speed.

Front

True or False: Any object with mass has gravity.

Back

True.

Front

What would happen to stars, planets, and all objects in the universe without gravity?

Back

They would move in a straight line.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect the force of gravity?

Back

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

Front

What is the relationship between gravity and orbits?

Back

Gravity keeps planets in orbit around stars by pulling them towards the star while their inertia keeps them moving forward.

Front

What is the formula for calculating gravitational force?

Back

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 role does the Sun's gravity play in the solar system?

Back

The Sun's gravity keeps the planets, asteroids, and comets in orbit around it.
