Potential or Kinetic Energy Worksheet? by Scorton Creek Publishing ... - Free Printable

To solve the problem of labeling each example as either potential energy or kinetic energy, we need to understand the definitions of these two types of energy:

1. Potential Energy: This is stored energy due to an object's position, configuration, or state. It has the potential to do work but is not actively doing so at the moment.
2. Kinetic Energy: This is the energy of motion. An object possesses kinetic energy when it is moving.

Now, let's analyze each scenario from the image and label them accordingly:

---

(M) A mouse trap set

- Analysis: The mouse trap is set but not triggered. The spring inside is compressed, storing energy that can be released when the trap is activated.
- Label: Potential Energy

---

(N) Car rolling down a hill

- Analysis: The car is in motion, rolling downhill. Since it is moving, it possesses kinetic energy.
- Label: Kinetic Energy

---

(O) A moving car

- Analysis: The car is explicitly described as "moving," indicating motion.
- Label: Kinetic Energy

---

(P) Person on playground swing with spring in compression position

- Analysis: The spring is compressed, meaning it is storing energy that can be released when the person swings forward. The person is not currently moving, so this is potential energy.
- Label: Potential Energy

---

(Q) A compound bow loaded and ready to shoot

- Analysis: The bow is loaded, meaning the string is pulled back and storing energy. This is potential energy because the arrow has not yet been released.
- Label: Potential Energy

---

(R) Pendulum bob at highest point

- Analysis: At the highest point of its swing, the pendulum bob is momentarily at rest. All its energy is stored as potential energy due to its height above the lowest point.
- Label: Potential Energy

---

(S) Arm and body ready to unwind

- Analysis: The arm and body are poised to move, indicating that energy is stored in the muscles and joints, ready to be released. This is potential energy.
- Label: Potential Energy

---

(T) Person on trampoline at highest point

- Analysis: At the highest point of the jump, the person is momentarily at rest. All their energy is stored as potential energy due to their height above the trampoline.
- Label: Potential Energy

---

(U) A roller coaster cart about to go down a steep drop

- Analysis: The roller coaster cart is at the top of the drop, stationary but ready to descend. Its energy is stored as potential energy due to its height.
- Label: Potential Energy

---

(V) A roller coaster cart moving halfway down the hill

- Analysis: The roller coaster cart is in motion, descending the hill. Since it is moving, it possesses kinetic energy.
- Label: Kinetic Energy

---

(W) A roller coaster cart moving at bottom

- Analysis: The roller coaster cart is at the bottom of the hill and is moving. Since it is in motion, it possesses kinetic energy.
- Label: Kinetic Energy

---

(X) A skydiver falling from a plane

- Analysis: The skydiver is in free fall, which means they are moving downward under the influence of gravity. This is kinetic energy.
- Label: Kinetic Energy

---

Final Labels:

- (M): Potential Energy
- (N): Kinetic Energy
- (O): Kinetic Energy
- (P): Potential Energy
- (Q): Potential Energy
- (R): Potential Energy
- (S): Potential Energy
- (T): Potential Energy
- (U): Potential Energy
- (V): Kinetic Energy
- (W): Kinetic Energy
- (X): Kinetic Energy

Summary:

- Potential Energy: (M), (P), (Q), (R), (S), (T), (U)
- Kinetic Energy: (N), (O), (V), (W), (X)

This completes the task of labeling each example correctly based on whether it represents potential or kinetic energy.
