Question

When the object move along the direction of its gravity force (gravity field), its potential energy reduces or increasesand the gravity force does object's kinetic energy (positive or negative) work, so that the increases or decreases) When the object move against the direction of its gravity force (gravity field), its potential energy__reduces or increases_ and the gravity force does object's kinetic energy (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/q-V (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 potential energy negative) work, so that the charge's kinetic energy (reduces or increases), and the E field does (increases 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/q-V (increase or decreases). (increase or decreases)

Explanation / Answer

When the object moves along the direction of gravity force,its potential energy reduces , and the gravity force does positive work ,so that the object's kinetic energy increases

When the object moves against the direction of gravity force,its potential energy increases , and the gravity force does negative work ,so that the object's kinetic energy reduces

Moving along the direction of the gravity force,gravitational potential energy U decreases

Moving along the direction of the gravity fireld,gravitational potential U/m increases

When a positive charge moves inside E along the direction of its electrical force(same as the E field direction),the potential energy reduces. and the E field does positive work so that the kinetic energy increases

When a positive charge moves inside E against the direction of its electrical force(same as the E field direction),the potential energy increases. and the E field does negative work so that the kinetic energy decreases

Moving along the direction of the E field force,electrical potential energy U decreases

Moving along the direction of the E field ,electrical potential U/q =V  decreases

When a negative charge moves inside E along the direction of its electrical force(opposite to its E force direction),the potential energy decreases. and the E field does positive work so that the kinetic energy increases

When a negative charge moves inside E along the direction of E field(opposite to its E force direction),the potential energy increases. and the E field does negative work so that the kinetic energy decreases

Moving along the direction of the E field force,electrical potential energy U  decreases

Moving along the direction of the E field,electrical potential U/q =V  increases
