Question 5 • HOPE Scholars- Science Grade 8

Which force helps keep Earth in orbit?

Answer
A
Earth’s gravity
B
the moon’s inertia
C
the Sun’s gravity
D
the Sun’s inertia

Explanation

The Sun’s gravity pulls Earth toward the Sun and provides the inward force that keeps Earth moving in its orbit. Earth’s inertia carries it forward, so together these effects produce its curved path around the Sun. The Sun’s inertia is not the force that keeps Earth in orbit.
