Which of the following would happen if the normal force and gravitational force acting on an object were unequal?
1. the object would move left or right.
2. the object would move up or down.
3. the mass of the object would increase.
4. the temperature of the object would decrease.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

thermal energy is the answer

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
