Where to Put Weights on Pinewood Derby Car
The weights on a Pinewood Derby car should be placed 1 inch in front of the rear axle, according to science.
This location provides the heaviest part of the car and increases potential energy and center of mass.
However, putting the weight too far back can cause instability.
Placing the weights near the front can give a slight head start or a smoother ride.
Field testers have found that placing the weights near the front can lead to better race results.
Ultimately, where to place weights on a Pinewood Derby car depends on personal preference and experimentation.
Did You Know?
1. Adding weights to a pinewood derby car can greatly affect its speed and stability, but did you know that the ideal placement for the weights is actually in the rear of the car? This helps distribute the weight evenly and maximize the car’s performance.
2. When deciding where to place the weights on a pinewood derby car, it’s important to take into account the center of gravity. You want the center of gravity to be as low as possible, so placing the weights closer to the bottom of the car, near the axle slots, can help achieve this balance and improve the car’s speed.
3. Contrary to popular belief, adding weights to the front of a pinewood derby car may actually hinder its performance. This can cause the car to “nose dive” and create excessive drag, slowing it down significantly.
4. An interesting technique to reduce the weight of a pinewood derby car is to drill a few holes underneath the body and fill them with a dense material, such as lead or tungsten. This allows you to strategically distribute the weight and refine the center of gravity for optimal speed.
5. Another little-known fact is that maximizing the weight of a pinewood derby car does not necessarily equate to better performance. In fact, the total weight limit is usually set for each competition, so it’s more about finding the right balance of weight and design to ensure the car meets all the requirements while still being competitive.
Weight Placement And Limitations
When constructing a Pinewood Derby car, weight placement is a crucial aspect to consider. The weight of the car is usually limited to 5 ounces. If your car weighs less than 5 ounces, you can add extra weights like coins to enhance its performance.
- Weight placement is important in Pinewood Derby car construction.
- The weight limit for a Pinewood Derby car is 5 ounces.
- Adding additional weights like coins can improve the car’s performance.

Importance Of Center Of Mass
Science tells us that the heaviest part of the car should be positioned approximately 1 inch in front of the rear axle. This ensures that the car’s center of mass is appropriately balanced, which is vital for stability and control during the race. By placing the weight closer to the rear of the car, you increase its potential energy, giving it the ability to accelerate more effectively.
However, it’s important not to place the weight too far back, as doing so can lead to instability during the race. Striking the right balance is crucial for optimal performance.
Benefits Of Placing Weight Near The Front
While placing the heaviest part of the car near the rear axle is considered ideal, there are potential advantages to placing some weight near the front of the car. This placement can provide a slight head start to the car or contribute to a smoother ride. Field testers have reported better race results when weight is distributed closer to the front.
Ultimately, the decision of where to place weight depends on personal preference and experimentation.

Tips For Adding And Adjusting Weights
To add weights to your Pinewood Derby car, it is recommended to install them before painting the car. This ensures that the weights are securely attached. It is crucial to add the weights until the total weight, including wheels and axles, reaches the 5-ounce limit.
If your car happens to weigh over 5 ounces, you can drill holes in the bottom of the block to remove excess wood and bring it within the weight limit. Precision and attention to detail are essential during this process to ensure the car remains balanced.
One popular option for additional weight is the zinc top weight, which weighs 2.2 ounces and can be aerodynamically attached to the top of the car. It is worth noting that the distribution of weight between the top and bottom of the car can affect its overall stability and speed.
Considerations For Different Types Of Weights
When selecting weights for your Pinewood Derby car, there are various options to consider. Lead wire weights are inexpensive, dense, and easy to work with. However, it’s crucial to acknowledge that lead is toxic, so always remember to use gloves when handling lead weights.
To cut the weights to the desired length, you can use a hacksaw, coping saw, or wire cutters. It’s recommended to use three weights of approximately the same length to achieve balanced weight distribution and maintain stability during the race.
In conclusion, the placement of weights on a Pinewood Derby car is crucial for its overall performance. Finding the optimal balance of weight distribution, with a focus on the center of mass, provides stability, control, and enhanced acceleration. Consider different types of weights, such as lead wire or top zinc weight, for customization and fine-tuning to achieve maximum speed.
By following these guidelines and conducting personal experimentation, you can optimize your Pinewood Derby car’s performance and increase your chances of success on the race track.
- Use lead wire weights for their affordability and density
- Always wear gloves when handling lead weights
- Cut weights to desired length using a hacksaw, coping saw, or wire cutters
- Use three weights of similar length for balanced weight distribution
- Place weights to focus on the center of mass for stability and control
- Consider different types of weights, such as lead wire or top zinc weight, for customization and fine-tuning of speed.

Frequently Asked Questions
Where should most of the weight be on a Pinewood Derby car?
According to the principles of physics, it is recommended to distribute the weight of a Pinewood Derby car towards the rear. Placing the majority of the weight approximately 1 inch in front of the rear axle maximizes the potential energy of the car. This positioning ensures that the center of mass remains higher up on the track, leading to increased performance and speed during the race.
Can you put weights on top of Pinewood Derby car?
While it may be tempting to add weights on top of a Pinewood Derby car, it is important to follow the recommended instructions to optimize performance. To ensure balance and stability, the weight should be mounted on the top of the car as far back as possible, without extending beyond the rear. Gluing the bottom weights, including the wheels and axles, to the block will help reach the desired weight of 5 oz. This careful approach is crucial to maintain the car’s aerodynamics and enhance its speed during the race.
Can weights go on bottom of Pinewood Derby car?
Yes, weights can be placed on the bottom of a Pinewood Derby car. In fact, two weights can be attached to the bottom, providing stability and improving the car’s overall balance. For cars that have varying widths, the weight can be divided into sections and rotated to fit. Moreover, these weights are versatile and can also be placed on the top or side of the car, allowing for various customization options. Whether stacking them or utilizing them in different positions, weights can be strategically used to optimize the performance of a Pinewood Derby car.
Should pinewood derby weights be high or low?
Pinewood Derby weights should ideally be placed towards the rear of the car for maximum speed. As per the Pinewood Derby rules, the weight limit for each car is 5 ounces. By strategically positioning the weights towards the back, it can enhance the car’s momentum and overall performance. This distribution of weight helps to optimize the car’s speed and ensure a competitive advantage during the race. With a substantial proportion of weight placed towards the rear, the pinewood derby car gains the potential to accelerate faster and maintain a consistent velocity throughout the race.
