sciman55 Posted March 30, 2006 Report Share Posted March 30, 2006 If you do not know, Jerk is the rate of change in acceleration. What happens when jerk changes the acceleration's magnitude when the object is changing speed? What happens when Jerk changes the acceleration's direction when the object changes direction? Also, does angular velocity and moment of inertia have any effect in changing direction? Quote Link to comment Share on other sites More sharing options...
Qfwfq Posted March 31, 2006 Report Share Posted March 31, 2006 Jerk is the rate of change in acceleration.Under this definition, acceleration is an initial value plus the time integral of Jerk, just like velocity is the initial value plus the time integral of acceleration. Much the same holds from velocity to position. If you want to work it out in direction, do the calculus with vectors. Moment of inertia counts for considering a body's rotation, if the acceleration is independent of this, it isn't influential. A rocket's thrust's direction is dependent on the way it is pointing. The force on a charge in a field depends on it's position in the field. Quote Link to comment Share on other sites More sharing options...
UncleAl Posted March 31, 2006 Report Share Posted March 31, 2006 The successive time derivatives of position: Position, velocity, acceleration, jerk, snap, crackle, and pop. The variables are sepatable. Quote Link to comment Share on other sites More sharing options...
