Step 1
Step 1: Recall Newton’s first law, which states that an object at rest stays at rest, and an object in motion continues in motion with constant velocity unless acted upon by a net external force. Show more…

1) When a box is horizontally pushed across a floor at a constant velocity, the amount of friction acting on the box is a) less than the pushing force. b) equal to the pushing force. c) greater than the pushing force. d. dependent on the speed of the sliding box 2) A measure of the amount of inertia is _________________. 3) A difference between Newton’s law of gravity and Coulomb’s law is that only one of these a. is a fundamental physical law. b. uses a proportionality constant. c. invokes the inverse-square law. d. involves repulsive as well as attractive forces.

a. Explain how Newton's first law of motion can be considered a consequence of Newton's second law? b. Aristotle stated that the speed of a falling body depends on its weight. Today We know that objects in free fall, regardless of their weight, have the same increased speed. Why doesn't weight affect acceleration? c. Some people say that the "force of inertia" (or the "force of impetus") throws passengers forward when a car brakes abruptly. What is wrong that explanation? d. What contains more apples, a 1 pound bag of them on Earth or a bag of apples? 1 pound of them on the moon? What contains more apples, a bag of 1 kilogram of them on Earth or a 1 Kilogram bag of them on the Moon? e. Your empty hand is not injured when you tap it gently against a wall. Why Will it be injured if you do it while holding a heavy load on it? What is Newton's law which is best applied here? Newton's law which is best applied here?
