The direction is what makes it positive or negative. This cookie is set by GDPR Cookie Consent plugin. The acceleration is 9.8 m/s2 everywhere, even when the velocity is zero at the top of the path. By calculating the slope of the velocity-time graph we get the value of acceleration. negative acceleration means the speed reduces with time. When an object is speeding up, the acceleration is in the same direction as the velocity. Thus, when the software finds and eliminates malware, the hackers would have already gained potential information from the users device.
