# How to Calculate Applied Force: A Comprehensive Guide

If you’ve ever wondered how to calculate the applied force on an object, you’re in luck. In this article, we will provide a step-by-step guide on how to determine the applied force, making use of fundamental physics concepts like Newton’s Laws of Motion.

**Requirements to Calculate Applied Force**

Before diving into the calculations, it’s essential to first understand the basic principles of applied force. Applied force can be defined as the external force exerted on an object that causes it to move or change its state of motion. To calculate applied force, you’ll need to be familiar with several concepts:

**1. Newton’s Second Law of Motion:** This law states that the net force acting on an object is equal to its mass multiplied by its acceleration (F = ma).

**2. Mass:** The mass (m) of an object is a measurement of how much matter it contains.

**3. Acceleration:** Acceleration (a) is a measure of how quickly an object’s velocity changes over time.

**4. Gravity:** The force of gravity acting on an object can also affect the applied force calculations.

**Step-By-Step Guide to Calculate Applied Force**

Now that you have a basic understanding of the concepts involved, follow these steps to calculate the applied force:

**1. Identify the mass and acceleration:** First, determine the mass and acceleration values for your problem. Mass is typically given in kilograms (kg), while acceleration should be in meters per second squared (m/s²).

**2. Determine any additional forces:** Sometimes, other forces such as gravity, friction, or tension come into play when calculating applied force. If there are any other forces involved in your problem, identify them and note their respective values.

**3. Apply Newton’s Second Law:** Use Newton’s Second Law of Motion (F = ma) as a foundation for calculating the total net force acting on an object.

**4. Add or subtract additional forces:** If your problem includes any other forces, like gravity or friction, calculate their effects on the net force and add or subtract them as necessary.

**5. Calculate applied force:** After accounting for all the forces acting on an object, you can now calculate the applied force itself. To do this, simply rearrange Newton’s Second Law equation (F = ma) to isolate applied force (F).

Example Calculation

To help illustrate these steps, let’s consider an example: a 10 kg object is being pushed across a horizontal surface with an acceleration of 2 m/s². How much force is being applied?

1. Mass and acceleration are given as m = 10 kg and a = 2 m/s².

2. Since there are no other forces mentioned in the problem, we can move forward to step three.

3. Apply Newton’s Second Law: F = ma = (10 kg)(2 m/s²).

4. Calculate the total net force: F = 20 N (Newton).

5. In this case, since there were no additional forces involved, the applied force is equal to the total net force: F_applied = F_net = 20 N.

**Conclusion**

Calculating applied force is essential for understanding various physics principles and real-world applications. By following these steps and using Newton’s Second Law of Motion as a foundation, you can accurately determine the applied force in any given scenario. Remember to consider all relevant forces and carefully account for their effects when making your calculations.
