  • A sheet of paper can be withdrawn from under a container of milk without toppling it if the paper is jerked quickly. This best demonstrates that
    the milk carton has inertia.

  • An object in mechanical equilibrium is an object
    that can be at rest or moving at a constant speed

  • The force of friction on a sliding object is 10 N. The applied force needed to maintain a constant velocity is
    10 N

  • A package falls off a truck that is moving at 30 m/s. Neglecting air resistance, the horizontal speed of the package just before it hits the ground is
    about 30 m/s

  • If your automobile runs out of fuel while you are driving, the engine stops but you do not come to an abrupt stop. The concept that most explains why is
    Inertia

  • According to Newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off. We never observe this because railroad trains
    always have forces that oppose their motion.

  • Whirl a rock at the end of a string and it follows a circular path. If the string breaks, the tendency of the rock is to
    follow a straight-line path.

  • When a rocket ship accelerating in outer space runs out of fuel, it
    no longer accelerates.

  • If no external forces are acting on a moving object, it will
    continue moving at the same velocity.
