Practice questions about Newton’s Universal gravity and weight.
A satellite is in orbit around the earth. If an additional module is attached to the satellite that triples its mass, what happens to the gravitational force that it experiences?
The space shuttle is working on a weather satellite at an orbit of 20,000m from the center of the earth. If it then increases its orbit to 40,000m in order to work on a GPS satellite, what happens to the gravitational force?
The space shuttle is working on a weather satellite at an orbit of 20,000m from the center of the earth. If it then increases its orbit to 100,000m in order to work on a GPS satellite, what happens to the gravitational force?
An alien spaceship orbiting around Earth at a height of 100,000m experiences a force from gravity of 25N. After lowering its orbit, the ship experiences a gravitational force of 100N. How high is its orbit now?
An alien spaceship orbiting around Earth at a height of 30,000m experiences a force from gravity of 10N. After lowering its orbit, the ship experiences a gravitational force of 90N. How high is its orbit now?
What is the weight of a bowling ball that has a mass of 6kg?
What is the mass of a person who has a weight of 490N?
If a table can support a weight of 1000 N, how many 2kg books can be stacked on it before it breaks?
