As the distance between an object and the center of the Earth is increased ... 1) the object's mass decreases and its weight remains the same. 2) both the object's mass and its weight remain the same. 3) both the obje...
The spring force is approximately zero and is shown as a red line. Positive force indicates wire attraction whereas negative force indicates wire repulsion. The derivations were done for a two-wire system where the displacement of the two wires was symmetric about their common mass center. The ...
8 A resultant force causes an object to accelerate. What is equal to the resultant force? A the acceleration of the object per unit mass B the change in kinetic energy of the object per unit time C the change in momentum of the object per unit time D the change in velocity of the ...
2.1(a) Explain why the acceleration of the sky-diver(i) is 10.0 ms2 at the start of the jump.[1(il) decreases with time,[2](b) At one point during the dive, the acceleration of the sky-diver was 7.5 ms2. The sky-diver and his equipment have a total mass of 90 kg.Determine ...
Gravitational Potential Energy: The gravitational potential energy is the amount of energy to overcome the gravitational work on the object to move an object from one position to another. This quantity is influenced by the object's mass and position. ...
In reality, however, the degree of differentiation decreases with size28. Partial differentiation has even been suggested for bodies as large as Charon29,30,31,32. The implications of this discrepancy are considered in the ʻDiscussionʼ. In any case, the smaller size of the impactors ...

The peripheral sensory organ adapts to the level of gravity by adjusting the mass of otoconia and the innervation of sensory epithelium. Understimulation, such as caused by microgravity, can delay the maturation of neural connections during the formation of the vestibular apparatus. "All toget...
How does Newton's second law of motion show the relationship (increase or decrease) between gravitational force, mass, and free-falling acceleration in a free-falling object (negligible of air resistance and the drag force being air)? If th...
Explain why the speed of an object decreases when an object is thrown upward using gravitational acceleration. How does changing the mass of an object affect the motion of free fall? How does the terminal speed of a parachutist be...
