We conclude that the weak and the mid-strong equivalence principle is still satisfied but the super-strong equivalence principle is not satisfied.
Introduction was made to the method of sine pulse width modulation (SPWM) wave generated by table searching, which is based on area equivalence principle.
What does the equivalence principle imply about accelerated motions and gravitational fields?
If the equivalence principle were violated, the moon's orbit around the Earth would appear skewed, either towards or away from the sun.
The equivalence principle,extensive general relativity and rest of general relativity;
The theoretical background of equivalence principle is briefly given, and the experimental tests of the equivalence principle is discussed in detail, via free-fall method and torsion balance.
