What do bathroom scales measure? When you stand on a bathroom scale, what happens to the scale? It depresses slightly.The scale contains springs that compress in proportion to your weight—similar to rubber bands expanding when pulled. Thesprings provide a measure of your weight (for an object which is not accelerating). This is a force in newtons (or pounds). Inmost countries, the measurement is divided by 9.80 to give a reading in mass units of kilograms. The scale measures weightbut is calibrated to provide information about mass. While standing on a bathroom scale, push down on a table next to you.What happens to the reading? Why? Would your scale measure the same “mass” on Earth as on the Moon?

You purchased 2.6 kg of apples from Wollaston. You noticed that they used a spring scale with the smallest division of 15.0 g to weigh them. What is the relative error in this weight measurement as a percentage?
Two forces act on a 2.90 kg object, the gravitational force and a second, constant force. The object starts from rest and in 1.20 s is displaced (4.10 3.30ĵ) m. Write the second force in unit vector notation. (Enter your answer in kg. m/s². Assume the gravitational force acts in the -ĵ direction.) kg. m/s² F
Newton's law of universal gravitation can be expressed by the equation Mm F= G where F is the gravitational force, M and m are masses, and ris a length. Force has the SI units kg · m/s2. What are the SI units of the proportionality constant G? m2 kg ·s m2 kg · s2 m3 kg . s2 m3 kg - s3
Which of the following statements are true of the quantity mass? List all that apply. The mass of an object is dependent upon the value of the acceleration of gravity. The standard metric unit of mass is the kilogram. Mass depends on how much stuff is present in an object. The mass of an object is variable and dependent upon its location. An object would have more mass on Mount Everest than the same object in the middle of Lake Michigan. People in Weight Watcher's are really concerned about their mass (they're mass watchers). The mass of an object can be measured in pounds. If all other variables are equal, then an object with a greater mass would have a more difficult time accelerating. If all other variables are equal, then it would require less exerted force to stop a less massive object than to stop a more massive object. The mass of an object is mathematically related to the weight of the object.
You purchased 5.8 kg of apples from Wollaston. You noticed that they used a spring scale with the smallest division of 8.6 g to weigh them. What is the relative error in this weight measurement as a percentage?[For example, if you find it to be 1.2% you should enter 1.2 in the answer box.]
Weight can be measured as the downward force an object exerts due to its mass times the gravitational pull of the Earth. A rock from the moon weighs 6.57 Newtons on Earth. How much did this rock weigh on the moon? The moon has a gravitational acceleration of 1.622 m/s.

Three crates with various contents are pulled by a force Fpull = 3595 N across a horizontal, frictionless roller-conveyor system. The group of boxes accelerates at 1.546 m/s² to the right. Between each adjacent pair of boxes is a force meter that measures the magnitude of the tension in the connecting rope. Between the box of mass mj and the box of mass m2, the force meter reads F12 = 1384 N. Between the box of mass mɔ and the box of mass m3, the force meter reads F23 = 2288 N.
