Battery stores or supplies charge to a circuit
Wrong belief
Battery contains charges that get used up and depleted. Misses that batteries supply energy difference, charge itself is conserved in the loop.
Correction
Battery does not store charges to send into the wire. It supplies energy by maintaining a potential difference; charge already in the circuit gets pushed around. Charge is conserved.

Heavier objects fall faster
Wrong belief
Believes mass affects how fast objects fall under gravity, ignoring that in vacuum all objects accelerate at g regardless of mass.
Correction
Without air resistance, all objects fall at the same rate g regardless of mass. Air drag, not gravity, is what differentiates feathers from bowling balls.
