Introduction

Acceleration due to gravity is a fundamental concept in physics that describes the rate at which an object falls towards the ground. It is a measure of the force of gravity acting on an object, and it is denoted by the symbol 'g'. In this article, we will explore the unit of acceleration due to gravity and discuss the different options available.

What is Acceleration Due to Gravity?

Acceleration due to gravity is the acceleration experienced by an object due to the force of gravity. It is a vector quantity, which means it has both magnitude and direction. The acceleration due to gravity is directed towards the center of the Earth and is proportional to the mass of the Earth and inversely proportional to the square of the distance from the center of the Earth.

Unit of Acceleration Due to Gravity

The unit of acceleration due to gravity is a measure of the rate at which an object falls towards the ground. It is typically denoted by the symbol 'g' and is measured in units of meters per second squared (m/s²). This unit represents the acceleration experienced by an object due to the force of gravity.

Analyzing the Options

Now that we have a clear understanding of the concept of acceleration due to gravity and its unit, let's analyze the options provided:

i. kg/m

This option represents the unit of mass per unit length. It is not a unit of acceleration due to gravity, but rather a unit of density.

ii. Nm²/kg²

This option represents the unit of force per unit mass squared. It is not a unit of acceleration due to gravity, but rather a unit of acceleration.

iii. kg/m³

This option represents the unit of mass per unit volume. It is not a unit of acceleration due to gravity, but rather a unit of density.

iv. m/s²

This option represents the unit of acceleration due to gravity. It is the correct unit of acceleration due to gravity, as it measures the rate at which an object falls towards the ground.

Conclusion

In conclusion, the unit of acceleration due to gravity is m/s². This unit represents the acceleration experienced by an object due to the force of gravity and is a fundamental concept in physics.

Key Takeaways

Acceleration due to gravity is a measure of the force of gravity acting on an object.
The unit of acceleration due to gravity is m/s².
The other options provided (kg/m, Nm²/kg², and kg/m³) are not units of acceleration due to gravity.
