The gravitational potential (V) is the potential energy (U) per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity. Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
It is recommended that you wait until you have missed a period to take a home test. A missed period is often one of the first signs of pregnancy. If you cannot wait that long to find out and you know the day you may have conceived, then the earliest you can take a test would be 14 days from possible conception.
1 Home pregnancy tests may test positive on the first day of a missed period, but almost all detect pregnancy 1 week after a missed period. 2  Call your doctor for an appointment if you test positive for pregnancy with a home test.
