Use 「後押し」 for a push from behind — encouragement or backing that gets someone moving, as in 「政府の後押し」 or 「決断を後押しする」; the figurative 「背中を押す」 works much the same. Cheer people on with 「応援」, send material or manpower aid as 「支援」, give formal sponsorship as 「後援」, and call a backer behind you 「後ろ盾」. For financial help, 「援助」 or 「助成」 fits. The opposites are 「邪魔」 and 「妨害」.
