Study Notes
Understanding Weight and Mass
- Weight refers to the force of gravity acting on an object, quantified by how strongly gravity pulls on that object's mass.
- Units of Measurement: Weight is commonly measured in Newtons (N).
- Formula for Weight: Weight can be calculated using the formula: Weight = mass x gravity, where gravity on Earth is approximately 9.8 m/s².
Key Differences Between Weight and Mass
- Mass represents the actual quantity of matter within an object and is measured in kilograms (kg), grams (g), etc.
- Independence of Mass: Mass remains constant regardless of the object's location in the universe, implying it does not change with the gravitational pull or environment.
- Weight Dependence: Weight varies based on the gravitational force acting on the object. For example, an object weighs less on the Moon due to lower gravity compared to Earth.
