Which would have greater effect on kinetic energy of an object doubling the mass or doubling the velocity?
the velocity is decreased
A change in a objects speed has a what effect on its kinetic energy than a change in mass?
Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
How would doubling the height of an object change the object's potential energy?
Also double since potential energy is the energy stored in a body due it's position.
Which would have greater effect on kinetic energy of an object - doubling the mass or doubling the velocity?
Doubling mass affects kinetic energy in that the greater the mass, the greater the kinetic energy. OK, but if you have a 10kg mass traveling at 2m/s and it bumps into and sticks to a 10g mass, the resultant speed would be 1m/s. The momentum stays the same. KE before is 10*2*2/2= 20, while the KE after is 20*1*1/2= 10. So it is not that the above answer is wrong, but rather, you question is not clear.
KE of an object when you double the velocity?
Kinetic energy = 1/2 (Mass) (Velocity)2. Since KE is proportional to V2, doubling the velocity increases KE by 22 = a factor of 4.

Doubling the speed. This is because the (non-relativistic) kinetic energy is proportional to the square of the speed.
Will leaving a force constant and doubling the mass of an object cause the acceleration to double?
Just the opposite. It will cause the acceleration to drop by 50%.
What type of reaction occurs and how does the mass of the object after rusting compared with its original mass?
1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.

What happen to the gravitional force when two objects mass dobles and the distance between objects double?
If you double the mass of the first object, double the mass of the second object, and double the distance between them, the gravitational forces between them are exactly the same as before all the doubling began.
Is doubling a kinetic energy source by mass bigger than when you double its speed?
Doubling the mass will double the kinetic energy. Doubling the speed will increase kinetic energy by a factor 22 = 4.

How is the influence of Earths gravity affected by the mass of an object?
The magnitude of the equal mutual forces of gravitation between the Earth and any object is proportional to the product of both their masses, so it's directly proportional to the mass of either one. The inescapable implication of this bold statement is the prediction that doubling an object's mass causes its weight on Earth to also double.
If someone shrunk the earth will there be less gravity?
No. Gravity depends on only two factors: mass and distance from the center of mass of the object. Gravity increases in proportion to the mass of the object and decreases in proportion tot he square of the distance from it. So doubling the mass doubles the gravity. Doubling distance cuts gravity to one quarter the original value. So, if you were to compress Earth to a smaller size without decreasing its mass, gravity where the surface originally was would remain the same. Gravity at the surface in its new position, closer to the center of mass would actually increase.
Does the size of an object change an object's density and why?
No. To calculate density you divide mass by volume (d = m/V) If you double the size of something (volume), then you are doubling the amount of it (mass). The whole reason for using density to compare things is because it is a property of the substance that does not change, regardless of quantity.
