While we think of weight as "mass", it is actually the pull of gravity on the object. For example, 4.5 kilograms (kg) near Earth is pulled with a force of about 45 newtons, that is, the same force we call "10 pounds" here in the U.S. where the metric system is not as familiar. Now put a 10 lb box at rest on a flat table. What is the total force on the box? mg That's the force of gravity downward on the box. 0 There is no net force on the box. The frictional force F which is μ mg N That's the normal force of the table pushing up on the box. How fast will an object be falling if dropped from rest and allowed to fall for 94 seconds? Use g = 10 m/s2 and give your answer in m/s
