What is jerk jolt in phyisics mean?
here is the definition from the Wikipedia, cut and paste: In physics, jerk, also known as jolt (especially in British English), surge and lurch, is the rate of change of acceleration; that is, the derivative of acceleration with respect to time, the second derivative of velocity, or the third derivative of position. Jerk is defined by any of the following equivalent expressions: \vec j=\frac {\mathrm{d} \vec a} {\mathrm{d}t}=\frac {\mathrm{d}^2 \vec v} {\mathrm{d}t^2}=\frac {\mathrm{d}^3 \vec s} {\mathrm{d}t^3} where \vec a is acceleration, \vec v is velocity, \vec s is position t is time. Jerk is a vector, and there is no generally used term to describe its scalar magnitude (e.g. “speed” as the scalar magnitude for velocity). The units of jerk are metres per second cubed (metres per second per second per second, m/s3 or m·s−3). There is no universal agreement on the symbol for jerk, but j is commonly used. ȧ, Newton’s notation for the derivative of acceleration, can also be used, espe
