Amplitude versus frequencyLoudness is a function of the sound wave's amplitude of the sound pressure. Aour ear drums are moved by the sound pressure.The greater the amplitude, the greater the volume. Pitch is related to its frequency. The higher the frequency, the higher the pitch.Loudness = amplitude of the sound pressureSoftest soundLoudest soundPitch = frequencyLowest pitchHighest pitch

The slope of the speed-vs-time graph is the magnitude of acceleration.
the slope show the velocity of the object which show its direction and magnitude.

From Figure 1, the velocity-versus-time graph of a particle in simple harmonic motion, we can infer the amplitude, period, and phase of the motion. The amplitude is the maximum velocity reached by the particle, the period is the time taken to complete one full cycle of motion, and the phase indicates the starting point of the motion within the cycle.
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
The magnitude of the slope is the radial speed: that is, the speed towards or away from the starting point. This is not the speed of the object because it takes no account of the component of motion in a direction perpendicular to the line joining the object to the starting point.
