How Much Force Does the Earth Exert on an 18-Kilogram Basket of Apples?

Have you ever wondered how much force the Earth exerts on a basket of apples weighing 18 kilograms? This seemingly simple question can lead to fascinating insights into the principles of physics, specifically gravitational force. In this article, we'll delve into the details of calculating the force and explore related concepts. We'll also provide you with some useful resources to help you understand more about the topic.

Understanding Weight and Force

The Earth's gravitational force is essentially the weight of any object placed on its surface. When you weigh an object, the scale you use is essentially measuring the force with which the Earth's gravitational field pulls the object towards its center. This force is calculated using the mass of the object and the acceleration due to gravity.

The formula for calculating weight (W) is:

W m times g

where (m) is the mass of the object and (g) is the acceleration due to gravity.

Calculating the Force

In the given scenario, the mass (m) of the basket of apples is 18 kilograms. The acceleration due to gravity (g) on the surface of the Earth is approximately 9.8 (m/s^2). Using the formula above, we can calculate the weight of the basket:

W 18 times 9.8 176.4 N

Therefore, the force exerted by the Earth on the basket of apples is approximately 176.4 Newtons (N).
