WebNegative acceleration means velocity is decreasing, and positive acceleration means velocity is increasing. It is important to note that negative acceleration does not always mean a decrease in speed. Since speed is the absolute value of velocity, we could have increasing or decreasing speed when acceleration is negative. WebKinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector.
