About Newton's Laws and Forces
- Car acceleration – The force from the engine determines how quickly your car speeds up.
- Sports – Kicking a soccer ball (the harder you kick, the greater the acceleration).
- Lifting objects – The force needed depends on the mass (weight) and how quickly you lift it.
- Gravitational: Pulls masses toward each other (e.g. gravity keeps us on Earth).
- Elastic (Spring): Restoring force from stretching/compressing a material.
- Friction: Opposes the motion between touching surfaces.
Mass – kilograms (kg), grams (g), pounds (lb)
Acceleration – meters/second² (m/s²), feet/second² (ft/s²), standard gravity (g)
- 1 N is the force needed to accelerate 1 kg by 1 m/s².
- 1 lbf ≈ 4.4482 N
- The gravitational force between you and the Earth is your weight.
Force Calculator – Instantly Calculate Force Using Mass & Acceleration
Want to calculate force without pulling out a physics book? Our Force Calculator helps you compute force (F) using mass and acceleration in just a few seconds. Whether you’re a student, engineer, or just curious, this tool makes Newton’s Second Law easy to apply.
🧠 What Is Force?
Force is a push or pull that causes an object to move, stop, or change direction. It’s measured in Newtons (N) and is a key part of Newton’s Second Law of Motion.
For example, when you push a shopping cart, you’re applying force. The heavier the cart (mass), the more force you need to accelerate it.
📐 Force Formula
The formula to calculate force is:
F = m × a
Where:
- F = Force (in Newtons)
- m = Mass (in kilograms)
- a = Acceleration (in m/s²)
This simple equation helps you solve countless physics problems.
🧮 How to Use the Force Calculator
- Enter the mass of the object (kg)
- Enter the acceleration (m/s²)
- Click Calculate
- Instantly get the force result in Newtons
You can also reverse the calculation to find mass or acceleration if force is known.
📊 Example Problem
Question: What is the force needed to accelerate a 10 kg object at 3 m/s²?
Solution:
F = m × a = 10 × 3 = 30 N
That means a 30 Newton force is needed to accelerate that object.
