Gravity and Motion

Question 2 • HOPE Scholars- Science Grade 8

Which statement best explains why objects are pulled toward Earth’s center?

Answer
A
Earth has a magnetic force that is strongest at its core.
B
Earth has a much greater mass than objects on its surface.
C
The weight of the atmosphere pushes objects toward Earth's surface.
D
The strength of the Sun’s gravity pushes down on objects at Earth's surface.

Explanation

Gravity is an attractive force between objects with mass. Earth’s mass is much greater than the mass of objects on its surface, so Earth’s gravitational pull draws them toward its center. Magnetism, air pressure, and the Sun’s gravity do not best explain this effect.
