Pilings are driven into the ground at a building site by dropping a 2050 kg object onto them. What change in gravitational potential energy does the object undergo if it is released from rest 17.5 m above the ground and ends up 1.00 m above the ground? change in gravitational potential energy: ___ J?

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
