Q: What is the equation for finding the gravitational force of an object?
A: F=MG
Q: An astronaut has a mass of 59 kilograms. What will her gravitational force be on the Moon? The gravitational attraction on the Moon is 1.62.
A: 95.58 N
Q: Which statement best describes the gravitational force of an object?
A:The greater the object’s mass and the closer it is, the greater its gravitational force.
Q: On Earth, the gravitational force of a robotic helicopter is 1.8 kilograms. What is the helicopter’s gravitational force on Mars?
A: 6.68 N
Q: Marcus wants to test the effect of gravity on objects with different masses. He drops two footballs from a first-floor window, a second-floor window, and a third-floor window. In each case, he times how long it takes the footballs to reach the ground. What is wrong with his experiment’s design?
A: It does not include objects with different masses.
Q: An astronaut drops two pieces of paper from the door of a lunar landing module. One piece of paper is crumpled, and the other piece is folded into an airplane. Why do the two pieces of paper land on the Moon’s surface at the same time?
A: The Moon has practically no atmosphere, so there is no air resistance.
Q: Why doesn’t an object falling from an airplane continue to accelerate?
A: Air resistance on the object will eventually equal the force of force of gravity.
Q: Which of the following descriptions best describes all of the factors that need to be considered when determining an object’s terminal velocity?
A: the object’s weight and area it presents, as well as air density
