Review Questions: Weight 1. The mass of an object on the Earth is 100 kg. What is the weight of the object on the Earth? Answer: a. b. What is the mass of the object on the moon? Answer: C. Assuming the acceleration due to gravity on the moon is exactly one-sixth of the acceleration due to gravity on Earth, what is the weight of the object on the moon? Answer 2. A man standing on the earth can exert the same force with his legs as when he is standing on the moon. We know that the mass of the man is the same on the Earth and the moon. We also know that F = ma is true on both the Earth and moon. Will the man be able to jump higher on the moon than the Earth? Why or why not? Answer:

Define mass in your own words. Define weight in your own words. Explain what would happen to your mass and weight if you were to go to the Moon. Justify your answer (explain your reasoning). What is the weight of a 50 kg object on Earth? A person weighs 500 N on Earth. What is the person’s mass? Find the person’s weight (from #5) if the person is on the Moon, which has a gravity of 1.63 m/s2. What is the weight of a 2.5 kg Chihuahua on Earth? What is the weight of a 75 kg person on Earth? Which amount of gold would you prefer to have and why? Gold #1 - Has a weight of 10 N on Earth Gold #2 - Has the weight of 4 N on the Moon
A group of engineers has landed on the moon, and they wish to determine the mass of some rocks. Theyhave a spring scale calibrated to read pounds mass at a location where the acceleration of gravity is 32.186 [ft/s2]. One of the moon rocks gives a reading of 18.76 on this scale. What is its mass? What is its weight on the moon? Take gmoon = 5.32 [ft/s2].
Gravity is a force of attraction between objects based on their mass and distance apart. Why aren't other objects, like your pencil, being pulled towards you. Explain reasoning.
Which of these is an expression for "g", the acceleration of gravity near Earth due to Earth's pull on another object. Pick those that apply. GMearth / R2 earth where "Earth " means mass and radius of the Earth GMsun / R2 sun where "Sun" means mass and radius of the Sun 9.8 m/s2 Fg / m where Fg is the force of gravity
While it is a widely accepted statement to say that the earth orbits the sun, this is technically incorrect. Use Newtons’ third law to explain why.
Newton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is F = GmM/r2 where G is the gravitational constant and r is the distance between the bodies. (a) Find dF/dr. What is the meaning of dF/dr? dF/dr represents the rate of change of the force with respect to the distance between the bodies. dF/dr represents the rate of change of the mass with respect to the distance between the bodies. dF/dr represents the rate of change of the distance between the bodies with respect to the force. dF/dr represents the rate of change of the mass with respect to the force. dF/dr represents the amount of force per distance. What does the minus sign indicate? The minus sign indicates that the force between the bodies is decreasing. The minus sign indicates that as the distance between the bodies increases, the magnitude of the force decreases. The minus sign indicates that as the distance between the bodies decreases, the…
