An object that is moving, will continue moving at the same speed in a straight line unless an outside force is strong enough to speed it up, slow it down, stop it, or cause it to change direction.” ]]> 2017-06-23 11:13:12 UTC https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288141 pearlynteoxy https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288295 The penny is at rest sitting on top of the card. Watch it as long as you like but, on it’s own, the penny will not move from that spot. When you flick the card out from under the penny, you allow gravity to act on it and drop it into the glass.
If you flick the card correctly, it simply slides out from between the glass and the penny. There’s not enough friction from the card to take the penny with it.]]> 2017-06-23 11:17:07 UTC https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288295 pearlynteoxy https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288450 This experiment also can work with more than just one coin. If a stack of coins is place on top of the playing card, the results will still be the same. The stack of coins will drop into the glass cup due to inertia. ]]> 2017-06-23 11:20:25 UTC https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288450 pearlynteoxy https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288899 2017-06-23 11:30:30 UTC https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/177288899 https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/181208671 2017-08-16 06:50:29 UTC https://padlet.com/pearlynteoxy/zbc603lcf4i1/wish/181208671
