11. The voltage generated in a sense coil on the mass by the magnet directly measures the instantaneous velocity of the ground. 12. This is what I was getting to with " instantaneous velocity ", which is the speed at any given time. 13. As momentum is instantaneous velocity times mass, this means that more massive objects gain and lose momentum more slowly than less massive objects. 14. In 2010, the instantaneous velocity of a Brownian particle ( a glass microsphere trapped in air with an optical tweezer ) was measured successfully. 15. The precession depends on " accelerated " motion, and the non-collinearity of the particle's instantaneous velocity and acceleration. 16. Your instantaneous velocity is 100 mph in whatever direction you are travelling at a particular moment, and your instantaneous speed is just 100 mph. 17. :: : Which is why you would take the limit as delta t approaches zero-giving the instantaneous velocity , dx / dt. 18. :: The original questioner might want to contemplate the conceptual difference between " velocity " and " instantaneous velocity ". 19. In considering motions of objects over time the instantaneous velocity of the object is the rate of change of the displacement as a function of time. 20. The kids have instantaneous velocities , but after colliding with each other and bouncing back to their seats the average velocity of the kids is zero.
