Which of the following form of energy is required to move the wheeled ...
Introduction:
The wheeled trolley is a device that requires energy to move. There are different forms of energy, but in this case, the required energy to move the wheeled trolley is mechanical energy.

Explanation:
Mechanical energy is the energy possessed by an object due to its motion or position. It is the energy associated with the movement or physical forces involved in an object's motion.

Reasoning:
To understand why mechanical energy is required to move the wheeled trolley, we need to consider the mechanism of the trolley itself. The trolley consists of wheels and axles, which allow it to roll. When a force is applied to the trolley, it overcomes the friction between the wheels and the surface, causing the trolley to move.

Key Points:
Here are some key points to consider regarding the use of mechanical energy to move the wheeled trolley:

1. Wheels and Axles: The trolley's wheels and axles are designed to reduce friction and allow smooth rolling motion. They provide the necessary mechanical advantage for motion.

2. Friction: Friction is the force that opposes motion between two surfaces in contact. When the trolley is stationary or at rest, friction acts as a resistance to movement. Mechanical energy is required to overcome this friction.

3. Applied Force: To move the wheeled trolley, an applied force is required. This force can be exerted by pushing or pulling the trolley, or by using another mechanism such as a motor or engine.

4. Conversion of Energy: The mechanical energy used to move the trolley can come from various sources. For example, if the trolley is pushed by a person, their muscle energy is converted into mechanical energy. If the trolley is powered by a motor, electrical energy is converted into mechanical energy.

5. Other Forms of Energy: While other forms of energy, such as electrical, solar, or heat energy, can be used to power the mechanisms that move the trolley, the energy ultimately needs to be converted into mechanical energy to overcome friction and move the trolley.

Conclusion:
In conclusion, the wheeled trolley requires mechanical energy to move. This is because mechanical energy is necessary to overcome friction and provide the necessary force for the trolley to roll. While other forms of energy can be used to power the mechanisms that move the trolley, they ultimately need to be converted into mechanical energy for the trolley to move.
