A hanging Slinky toy is attached to a powerful battery and a switch. When the switch is closed so that the toy now carries current, does the Slinky compress or expand?

(delta)d = V * (delta)t (delta)t = (delta)d / V V= (delta)d / (delta)t -Relative velocity :- Velocity of an object added to the velocity of a frame. -Simultaneous motion :- When an object moves 2 dimensions (directions) at the same time. -Frame :- ‘Box” in which the object moves. ____________________________________________________ Chapter 10: Acceleration -Acceleration :- The change in an object’s velocity divided by the change in time a= (delta)v / (delta)t Acceleration due to Gravity on Earth 1
