Speed, unlike acceleration or velocity, does NOT specify **Direction**.

Speed is a scalar quantity that only measures how fast something is moving, without regard to the direction of movement. In contrast, velocity is a vector quantity that includes both speed and direction.

The example that shows an object acted on by two balanced forces is **A car moving at a constant speed in a constant direction**.

In this case, balanced forces mean that the net force acting on the car is zero, resulting in the car moving at a constant speed without acceleration. The other examples involve unbalanced forces that result in changes in speed or direction.

To measure average speed, the required data is **The distance traveled and the time spent**.

Average speed is calculated by dividing the total distance traveled by the total time taken for that travel.
