What is gravity and how do you calculate weight based on mass?
Understand the Problem
The question is asking about gravitational force, weight, and how to calculate the weight of different masses given a gravitational field strength. It is likely seeking explanations on the relations between weight, mass, and the gravitational field.
Answer
Gravity is the force of attraction; weight = mass × gravity (W = mg).
The final answer is that gravity is the force of attraction between masses, and weight is calculated by multiplying mass by gravitational acceleration (W = mg).
Answer for screen readers
The final answer is that gravity is the force of attraction between masses, and weight is calculated by multiplying mass by gravitational acceleration (W = mg).
More Information
Gravity is a fundamental force that attracts two bodies with mass. Earth's surface gravity is approximately 9.8 m/s², influencing how weight is perceived here.
Tips
A common mistake is confusing mass with weight. Mass is constant regardless of location, while weight varies with gravitational field strength.
