Weight Formula:
From: | To: |
The weight formula calculates the force exerted by an object due to gravity. Weight is a force measured in Newtons (N) and is calculated by multiplying an object's mass by the gravitational acceleration.
The calculator uses the weight formula:
Where:
Explanation: This formula represents Newton's second law of motion applied to gravitational force, where weight is proportional to both mass and gravitational acceleration.
Details: Calculating weight is fundamental in physics, engineering, and everyday applications. It helps determine the force objects exert on surfaces, structural load requirements, and is essential for various scientific calculations.
Tips: Enter mass in kilograms and gravitational acceleration in m/s². Standard Earth gravity is approximately 9.81 m/s². All values must be positive numbers.
Q1: What's the difference between mass and weight?
A: Mass is the amount of matter in an object (measured in kg), while weight is the force exerted by gravity on that mass (measured in N).
Q2: Why does weight vary on different planets?
A: Weight varies because gravitational acceleration (g) differs on different celestial bodies, while mass remains constant.
Q3: What is standard Earth gravity?
A: Standard Earth gravity is approximately 9.81 m/s², though it varies slightly depending on location and altitude.
Q4: How is weight different from force?
A: Weight is a specific type of force - specifically, the gravitational force acting on an object's mass.
Q5: Can weight be zero?
A: In free-fall or zero-gravity environments (like orbit), objects experience weightlessness, meaning their weight approaches zero while mass remains unchanged.
