Answer:
The true statements are: A, D
Explanation:
This interesting problem of the conceptual relationship between mass and weight, the equation for weight is
W = m g
From Newton's second law
W = ma
Where g the acceleration of gravity, this acceleration can vary at several points, for example, in a vertical circumference the acceleration of gravity is always down and the centripetal acceleration continuously changes direction therefore the body weight constantly changes from zero to the maximum value.
The mass instead is always the same and is the resistance (inertia) to the movement of the bodies
Of the aforementioned the peo has the unit mass multiplied by the acceleration
Weight [N] = mass [kg] acceleration [m / s2]
Weight [lb] = mass [slug] acceleration [ft / s2]
Examine the statements
A) 12.0 lb. True pounds are the mass for acceleration. English measurement system
B) 0.34g False. Grams are units of mass,
C) 120 kg. False. The kilograms is a multiple of the grams, which are units of mass
D) 1600 kN True the newton is the unit of weight, the Newton kilo is a multiple
E) 0.34 m False meters are units of length
F) 411 cm False centimeters is a submultiple of the meter that is a unit of length
