It is the acceleration.
If the graph of speed versus time is a straight line, then the acceleration is constant/uniform. If the graph is curved or has a sharp corner, the acceleration is non-uniform, i.e. not constant. A uniform acceleration means the speed changes by fixed amount every unit of time, e.g. +3 m/s every second.
The speed at which an object falls and the acceleration at which it falls are not the same value. The acceleration due to gravity is constant at about 9.8 m/s^2 near the surface of the Earth, but the speed of an object can change as it falls depending on factors such as air resistance.
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.

Speed increases when a body accelerates under the influence of a force. Newton's second law: acceleration= force/mass. Acceleration is the rate of change of speed over a period of time. For example if you drop an object, it's speed increases by 9.8 meters per second every second.

It is a measure of acceleration. Every hour, the speed increases by 343 metres per second.
In free fall, the speed of an object increases by 9.8 meters per second every second, due to the acceleration of gravity. This acceleration is constant near the surface of the Earth, making the speed increase steadily.

Galileo discovered that the speed gained by a ball rolling down an inclined plane is constant and increases linearly with time. This led to the development of the concept of acceleration, where an object's speed changes at a constant rate over time.
It increases by 20 centimetres per second in the given direction for each second that elapses.
