Drag each label to the correct location. Sort the sentences based on whether energy is stored or not stored in the situation described.

Energy stored:A spring compresses and returns

to its original shape when released.An object lifted with a pulley drops

down when the rope is released.

Energy not stored:A boat travels through water

(and air) and doesn’t move

after stopping.A box is pushed and doesn’t

move after the pushing stops.

Explanation:

We store energy in a spring when we compress it. When we release the spring, it returns to its original shape. The stored energy changes into kinetic energy. When a pulley lifts an object, the object gains stored energy. This stored energy changes to kinetic energy when the rope is released. A boat moving on water doesn’t store energy. Its kinetic energy is transformed to thermal energy because of drag. For the same reason, pushing a box on a table against friction doesn’t store energy either.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
