Question

hen the object move along the direction of its gravity force (gravity field), its potential energy_reduces or a increases object's kinetic energy and the gravity force does (positive or negative) work, so that the When the object move against the direction of its gravity force (gravity field), its potential energy reduces or increases object's kinetic enerey and the gravity force does (positive or negative) work, so that the (increases or decreases). Moving along the direction of the gravity force, gravitational potential energy U Moving along the direction of the gravity FIELD, gravitational potential U/m (increase or decreases). (increase or decreases). The exact same conclusions can be applied to positive charges in the electrical field. When a positive charge move inside E field along the direction of its Electrical force (same as the E field direction) the potential energy negative) work, so that the charge's kinetic energy (reduces or increases), and the E field does(positive or (increases or decreases). When a positive charge move inside E field against the direction of its Electrical force (same as the E field direction), the potential energy -(reduces or increases), and the E field does (positive or negative) work, so that the charge's kinetic energy- (increases or decreases). (increase or decreases). Moving along the direction of the E field force, electrical potential energy U Moving along the direction of the E FIELD, electrical potential U/qsV (increase or decreases). For negative charges in the electrical field, most the answers may be different. When a negative charge move inside E field along the direction of its Electrical force (opposite to the E field direction), the potential energy (reduces or increases), and the E field does (positive or negative) work, so that the charge's kinetic energy (increases or decreases) When a negative charge move inside E field along the direction of E field (opposite to its E force direction), the (positive or (reduces or increases), and the E field does potential energy negative) work, so that the charge's kinetic energy --(increases or decreases). Moving along the direction of the E field force, electrical potential energy U(increase or decreases. Moving along the direction of the E FIELD, electrical potential U/q V (increase or decreases).
