Force vs Mass
公式
## Newton's Second Law of Motion Force equals the product of mass and acceleration. ### Formula **F = m * a** The SI unit of force is the newton (N), equivalent to 1 kg * m/s².
计算示例
Find the force on a 10 kg object accelerating at 9.81 m/s².
- 01F = m * a
- 02F = 10 * 9.81
- 03F = 98.1 N
常见问题
What is a newton?
One newton is the force needed to accelerate a 1 kg mass by 1 m/s². It is the SI unit of force.
Does this calculator handle weight?
Yes. Weight is the force of gravity on an object: W = m * g, where g is approximately 9.81 m/s² on Earth.
What if multiple forces act on an object?
The net force is the vector sum of all individual forces. This net force determines the acceleration via F_net = m * a.
