gravity and orbits

Front

What is gravity?

Back

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

Front

What is an orbit?

Back

An orbit is the curved path of an object around a point or object in space, such as a planet around the sun.

Front

What does Kepler's first law state?

Back

Kepler's first law states that planets orbit the sun in elliptical orbits, with the sun located at one focus.

Front

How does mass affect gravitational attraction?

Back

The gravitational attraction between two objects increases with the mass of the objects; a more massive object exerts a stronger gravitational pull.

Front

What happens to the speed of a planet as it gets closer to the sun?

Back

A planet travels faster when it is closer to the sun due to the stronger gravitational pull.

Front

What is the relationship between distance and gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of an object around its own axis, while revolution is the movement of an object around another object.

Front

What is the significance of the sun in our solar system?

Back

The sun is the center of our solar system, and its gravitational force keeps the planets in orbit around it.

Front

What is an elliptical orbit?

Back

An elliptical orbit is an oval-shaped path that an object follows as it revolves around another object in space.

Front

What is the effect of gravity on satellites?

Back

Gravity keeps satellites in orbit around Earth, balancing their forward motion with the pull of Earth's gravity.
