UG A Checkpoint 1/5

Front

What is perihelion?

Back

The point in the Earth's orbit where it is closest to the sun and moves the fastest.

Front

What is the formula for gravitational force?

Back

F_g= G (m₁m₂)/r²

Front

What happens to the force of gravity when the distance between two objects is halved?

Back

The force of gravity will quadruple.

Front

What is the value of the Universal Gravitation Constant (G)?

Back

6.67 x 10^-11 Nm²/kg²

Front

What is the average distance between the sun and the Earth in astronomical units (AU)?

Back

1 AU (93 million miles)

Front

What is aphelion?

Back

The point in the Earth's orbit where it is farthest from the sun.

Front

What does the gravitational force depend on?

Back

The mass of the objects and the distance between them.

Front

How does mass affect gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

What is the relationship between distance and gravitational force?

Back

As distance increases, gravitational force decreases.

Front

What is the significance of the gravitational constant (G)?

Back

It quantifies the strength of the gravitational force between two masses.
