Q.1
The gravitational pull is greater between two objects that
  • have greater masses.
  • have rougher surfaces.
  • are farther apart.
  • are moving at greater speed
Q.2
Which of the following explains the difference between speed and velocity?
  • One has motion, and the other does not.
  • One has direction, and the other does not.
  • One involves time, and the other does not.
  • One involves acceleration, and the other does not.
Q.3
A sled sliding on a flat, icy surface with a constant velocity is best described by
  • Newton’s first law of motion for objects at rest.
  • Newton’s first law of motion for objects in motion.
  • Newton’s second law of motion.
  • Newton’s third law of motion.
Q.4
An ice skater at rest pushes against a sled at rest, causing both the skater and sled to move away from each other with different accelerations. This is an example best described by
  • Newton’s first law of motion for objects at rest.
  • Newton’s first law of motion for objects in motion.
  • Newton’s second law of motion.
  • Newton’s third law of motion.
Q.5
According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will
  • remain in motion.
  • eventually come to a stop.
  • change its momentum.
  • accelerate.
Q.6
A crumpled piece of paper hits the ground before a flat sheet of paper because
  • the acceleration of gravity is greater on the  crumpled paper.
  • there is more air resistance against the flat paper.
  • the crumpled paper is more massive
  • the crumpled paper is less massive.
Q.7
If an action force is a cue ball (white) hitting a billiard ball (various colors) when playing pool, then the reaction force is
  • exerted on the table
  • exerted on all the other billiard balls.
  • not present
  • exerted by the billiard ball on the cue ball.
Q.8
If a baseball and a cannonball are dropped from the same height at the same time, which ball will hit the ground first?
