Bullet Fired vs Bullet Dropped - Mythbusters for the Impatient
Mythbusters for the Impatient・2 minutes read
In a physics experiment, two bullets—one dropped and the other fired—hit the ground simultaneously from 360 feet, illustrating that gravity impacts them equally. High-speed footage reveals a minuscule difference in landing times of just 39.6 milliseconds, underscoring the experiment's precision in comparison to the human eye's perception limits.
Insights
- The physics experiment shows that gravity affects objects equally regardless of their initial motion, as demonstrated by the simultaneous release of a dropped bullet and a fired bullet, both hitting the ground from a height of 360 feet at the same time. This outcome emphasizes that the absence of lift, rather than the speed of the fired bullet, determines the effect of gravity on its descent.
- Analysis of the high-speed footage reveals that the difference in landing times between the two bullets is just 39.6 milliseconds, a duration too brief for the human eye to detect, highlighting the experiment's precision. This time difference is shorter than the duration of a single frame in a standard film, illustrating the advanced technology used to capture such rapid events and the subtlety of motion in gravitational experiments.

Recent questions
What is gravity in simple terms?
Gravity is a natural force that attracts objects toward each other. It is what keeps us grounded on Earth and causes objects to fall when dropped. The strength of gravity depends on the mass of the objects and the distance between them. For example, the Earth’s gravity pulls everything towards its center, which is why when you drop something, it falls to the ground. This force is essential for many phenomena in the universe, including the orbits of planets around stars and the formation of galaxies.
How do I improve my focus?
Improving focus can be achieved through several strategies. First, creating a distraction-free environment is crucial; this means minimizing noise and clutter around you. Setting specific goals can also help, as having clear objectives gives you a direction to concentrate on. Additionally, taking regular breaks can prevent burnout and maintain your mental energy. Techniques such as mindfulness and meditation can enhance your ability to focus by training your mind to stay present. Lastly, ensuring you get enough sleep and maintain a healthy diet can significantly impact your cognitive functions, including focus.
What are the benefits of meditation?
Meditation offers numerous benefits for both mental and physical health. It can reduce stress and anxiety by promoting relaxation and helping individuals manage their thoughts more effectively. Regular practice has been shown to improve concentration and attention span, making it easier to focus on tasks. Additionally, meditation can enhance emotional well-being by fostering a greater sense of self-awareness and promoting a positive outlook on life. Physically, it may lower blood pressure and improve sleep quality, contributing to overall health. Many people find that incorporating meditation into their daily routine leads to a more balanced and fulfilling life.
What is the best way to learn a language?
The best way to learn a language involves a combination of methods tailored to your learning style. Immersion is highly effective; surrounding yourself with the language through conversation, media, and culture accelerates learning. Consistent practice is key, so engaging in daily exercises, such as vocabulary drills and speaking with native speakers, can enhance retention. Utilizing language learning apps and online resources can provide structured lessons and interactive experiences. Additionally, setting realistic goals and tracking your progress can keep you motivated. Ultimately, finding enjoyable ways to practice, such as through music or travel, can make the learning process more engaging and effective.
What are the signs of burnout?
Signs of burnout can manifest in various ways, affecting both mental and physical health. Common symptoms include chronic fatigue, a sense of detachment from work or responsibilities, and feelings of ineffectiveness or lack of accomplishment. Individuals may also experience irritability, changes in sleep patterns, and difficulty concentrating. Physical symptoms can include headaches, gastrointestinal issues, and a weakened immune system. Recognizing these signs early is crucial, as burnout can lead to more severe health problems if not addressed. Taking proactive steps, such as seeking support, setting boundaries, and prioritizing self-care, can help mitigate the effects of burnout and promote recovery.

Gravity's Equal Impact on Falling Bullets
- In a physics experiment, two bullets are released simultaneously from the same height: one is dropped, and the other is fired from a gun. Both bullets hit the ground at the same time, demonstrating that gravity affects them equally, as the fired bullet has no lift due to the absence of wings. The experiment is conducted using a high-speed camera and a drop rig, with the bullets released from a height of 360 feet.
- The analysis of the high-speed footage reveals that the difference in landing times between the two bullets is 39.6 milliseconds, which is shorter than the human eye's ability to perceive. To contextualize this, 39.6 milliseconds is less than the duration of a single frame in a 24 frames-per-second film, which is displayed for 1/24th of a second (approximately 41.67 milliseconds), illustrating the remarkable precision of the experiment.
