How to Calculate Work Done Against Gravity: A Simple Guide
Learn to calculate work against gravity with our formula: Work = Mass x Gravity x Height. Understand energy requirements easily!
48 views
Calculating work from gravity involves using the formula: Work = Mass x Gravity x Height. Here, mass (m) is in kilograms, gravity (g) is approximately 9.8 m/s², and height (h) is in meters. For example, lifting a 10 kg object up 2 meters would be: Work = 10 kg x 9.8 m/s² x 2 m = 196 Joules. This formula helps in understanding the energy needed to move objects against gravity.
FAQs & Answers
- What is the formula for calculating work against gravity? The formula for calculating work against gravity is Work = Mass x Gravity x Height, where mass is in kilograms, gravity is approximately 9.8 m/s², and height is in meters.
- How do you calculate work done in joules when lifting an object? To calculate work done in joules when lifting an object, multiply the object's mass (in kg) by the acceleration due to gravity (9.8 m/s²) and the height (in meters) the object is lifted.
- What is the value of gravity used in work calculations? The standard value of gravity used in work calculations is approximately 9.8 m/s².
- Can work be negative when calculating against gravity? Yes, work can be considered negative if the force applied is in the opposite direction to the movement of the object, such as when an object is falling.
