Which of the following are two examples of ways that objects can have potential energy?

A boulder that is falling after being pushed off a cliff.

A Iron nail as it move towards
a magnet.

A pebble in a slingshot before it has been shot.

A pebble traveling as it is shot with a slingshot.

Answer 1

Your two answers would be 'An iron nail as it moves towards a magnet' and 'A pebble in a slingshot before it has been shot'.

Step-by-step explanation:

Potential energy is energy stored for when the kinetic energy needs to be released. Kinetic energy is released when objects are in full motion.

Options A and D (The boulder one and the pebble traveling as it is shot) imply that the objects are moving and already using kinetic energy. Therefore, the other two options B and D, stated in the answer box, make the most sense.

Answer 2

A: A boulder that is falling after being pushed off a cliff.

C: A pebble in a slingshot before it has been shot.

Step-by-step explanation:

These are examples of potential energy because they are holding energy before it is released.

Hope this helps
