If your car won't accelerate but the RPMs go up, it could be due to a slipping clutch (in manual transmissions) or a faulty torque converter (in automatics). Another possibility is a problem with the transmission fluid; it may be low or degraded. Check for any warning lights on the dashboard and consider having a mechanic perform a diagnostic test to identify the exact issue.
