In mathematics, the weight formula is used to calculate the force exerted by gravity on an object. The weight of an object is the product of its mass and the acceleration due to gravity. In this topic, we will learn the formula for weight and its importance in various fields.
The weight of an object is determined by its mass and the gravitational pull acting on it. Let’s learn the formula to calculate the weight.
The weight is the force exerted by gravity on an object. It is calculated using the formula:
Weight formula: Weight(W) = Mass (m) × Gravitational acceleration (g), where the gravitational acceleration is typically ( 9.8 \, {m/s}2 ) on Earth.
The weight formula is essential in physics and engineering to understand the force exerted by gravity. Here are some important uses of the weight formula:
Students often find physics formulas tricky. Here are some tips and tricks to master the weight formula:
In real life, the weight formula is crucial in various fields. Here are some applications:
Students often make errors when calculating weight. Here are some mistakes and ways to avoid them:
Calculate the weight of a 10 kg object on Earth.
The weight is 98 N
To find the weight, use the formula:
Weight = mass × gravitational acceleration
= 10 kg × 9.8 m/s²
= 98 N
What is the weight of a 5 kg object on the Moon, where gravity is \( 1.6 \, \text{m/s}^2 \)?
The weight is 8 N
To find the weight, use the formula:
Weight = mass × gravitational acceleration
= 5 kg × 1.6 m/s²
= 8 N
A 50 kg object is taken to a planet where gravity is \( 15 \, \text{m/s}^2 \). What is its weight there?
The weight is 750 N
To find the weight, use the formula:
Weight = mass × gravitational acceleration
= 50 kg × 15 m/s²
= 750 N
