What is the term for the force that pulls objects toward the center of the Earth?

Correct answer

Gravity

  1. A Gravity
  2. B Inertia
  3. C Friction
  4. D Magnetism

Why this is the answer

GRAVITY is the force that pulls objects toward the center of the Earth (and that attracts masses to each other generally). ASVAB General Science/physics covers basic forces. Near Earth's surface, gravity accelerates falling objects at about 9.8 m/s². Other concepts: FRICTION (resists motion between surfaces); MAGNETISM (attraction/repulsion of magnetic materials); INERTIA (an object's resistance to a change in motion — Newton's first law). Gravity as the force pulling objects toward Earth is a fundamental, commonly tested concept.

About this topic: Physics

Physics questions cover motion, forces, Newton's laws, energy, heat, sound, light and basic electricity. Units and simple relationships (speed = distance ÷ time, F = ma) are tested more than calculation. This is one of 15 General Science questions on physics, each with a full explanation on a single study page.
