To solve this problem, we need to distinguish between
potential energy and
kinetic energy based on the given scenarios. Here's a step-by-step explanation:
Definitions Recap:
-
Potential Energy: Stored energy that is waiting to work. It depends on the position or state of an object.
-
Kinetic Energy: Energy that is working because the object is in motion.
Solution:
1.
The apple in the table is _______ energy.
- The apple is stationary and has the potential to fall due to its height above the ground. This is
potential energy.
-
Answer: Potential Energy
2.
The apple falling from the table is _______ energy.
- The apple is in motion as it falls. This is
kinetic energy.
-
Answer: Kinetic Energy
3.
