ASTRO 7N test 1Newton's first law - correct answer An object at rest, or in motion in a straight line at a constant speed, will remain in that state unless acted upon by a force. (example: If the Sun suddenly disappeared, the Earth would continue in the direction that it was traveling in its orbit at that time.) Newton's second law - correct answer The acceleration of a body due to a force will be in the same direction as the force, with a magnitude inversely proportional to its mass. •...
