Front

What defines velocity?

Back

Speed combined with direction of motion.

Front

What is centripetal acceleration?

Back

The acceleration directed towards the center of a circular path, calculated as a = v²/r.

Front

How do you calculate centripetal acceleration?

Back

Centripetal acceleration (a) = (angular speed)² × radius.

Front

What is the formula for orbital velocity?

Back

Orbital velocity (v) = √(G × M / r), where G is the gravitational constant, M is the mass of the planet, and r is the distance from the center of the planet.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)².

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with mass and decreases with distance.

Front

What is the formula for gravitational force?

Back

F = G × (m1 × m2) / r².

Front

What is a synchronous orbit?

Back

An orbit where a satellite's orbital period matches the rotation period of the planet.

Front

How do you find the height of a synchronous orbit above a planet's surface?

Back

Height = (G × M × T² / (4π²))^(1/3) - radius of the planet.

Front

What is the radius of a planet?

Back

The distance from the center of the planet to its surface.
