What quantities does angular momentum depend upon?
Momentum depends on speed and mass. A train moving at 20 mph has more momentum than a bicyclist moving at the same speed.
Why are astronauts weightless in the space station quizlet?
Why are astronauts weightless in the space station? because they are in a constant state of free fall around the Earth. Newton’s 1st law: An object remains in motion at constant velocity, or remains at rest, unless acted upon by a net force.
Why is your weight less on the moon than on Earth but your mass is the same quizlet?
The moon’s mass is much smaller than earth’s mass. Since the force of gravitational attraction between two objects depends on the mass of both objects, the force of gravitational attraction between you and the moon would therefore be smaller than the force between you and the Earth.
What is the difference between mass and weight in science?
Your mass is the same no matter where you go in the universe; your weight, on the other hand, changes from place to place. Mass is measured in kilograms; even though we usually talk about weight in kilograms, strictly speaking it should be measured in newtons, the units of force.
Which remains the same size as the distance of an object from Earth changes?
weight has to do with the gravitational pull, as distance from earth decreases, so does the gravitational pull. meaning, the size of the force, the pull, and the weight would all change. mass stays the same (in this sense.
What will be the effect on force of gravitation if both masses are doubled and distance is halved?
Answer. Answer: (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times.
Why does gravitational force does not depend on medium?
Gravitational force does not depend on medium because gravity is unipolar. Electric charges have two polarities, so an electric field polarises the medium it goes through. But gravity comes in only one polarity, attractive, so when it goes through a medium, there is no polarising effect or polarising forces.
