Explanation:

Question 7

In a position - time graph, the position of the object is plotted against time. If the position value (y - coordinate) increases with time (x - coordinate), the object is moving in the positive direction relative to the starting position. If the position value decreases with time, the object is moving in the negative direction relative to the starting position.

Speed is defined as the rate at which an object moves. It quantifies how fast or slow an object is moving. Mathematically, speed \(v=\frac{d}{t}\), where \(d\) is the distance traveled and \(t\) is the time taken.

The SI (International System of Units) unit for speed is derived from the SI units of distance (meter, \(m\)) and time (second, \(s\)). Using the formula \(v = \frac{d}{t}\), when \(d\) is in meters and \(t\) is in seconds, the unit of speed is meters per second (\(m/s\)).

True
