What is the formula to calculate the weight of an object?
Show answer & explanation
Correct answer: A
Explanation
Correct Answer:
Option 1: W = m × g
Explanation:
Weight is the force exerted on an object due to gravity. The formula is W = m × g, where m is mass and g is acceleration due to gravity (≈ 9.8 m/s² on Earth). Weight is a vector quantity, while mass is scalar. Weight changes with location, unlike mass.
