Unit 3 - 3.3 Orbital Motion

Front

What is the relationship between orbital radius (R) and period (T) for planets in orbit?

Back

Front

What is escape velocity?

Back

Escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a celestial body, approximately 11.2 km/s for Earth.

Front

How does the mass of a satellite affect its orbital speed?

Back

The mass of a satellite does not affect its orbital speed; orbital speed depends on the radius of the orbit and the mass of the central body.

Front

What is the formula for calculating the orbital speed of a satellite?

Back

Front

Which planet has the fastest orbital speed in our solar system?

Back

Mercury has the fastest orbital speed due to its proximity to the Sun.

Front

What is the significance of the orbital period of a planet?

Back

The orbital period is the time it takes for a planet to complete one full orbit around the Sun, which varies based on the planet's distance from the Sun.

Front

What happens to the orbital speed of a planet as its distance from the Sun increases?

Back

As the distance from the Sun increases, the orbital speed of the planet decreases.

Front

What is the relationship between orbital radius and period for a satellite in a circular orbit?

Back

Front

What is the effect of increasing the radius of an orbit on the orbital period?

Back

Increasing the radius of an orbit results in a longer orbital period.

What is the formula for gravitational force between two masses?
