Question

What object is being acted on by balanced forces?
A. A snowflake that falls and lands on a roof
B. A skateboard that rolls increasingly faster down a hill
C. A baseball that rolls to a stop in a field
D. A car that moves at a constant speed in one direction

Answer 1

Answer: D . A car that moves at a constant speed in one direction.

Explanation: D is the answer because a car moving in a constant speed represents a balance force because the speed is constant and the forces are balanced or , when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts.
