When we talk about measuring force in physics, there are some important units you need to know. Here are the main ones:
Newton (N): This is the main unit of force used in the metric system.
One newton is the amount of force needed to make one kilogram move faster by one meter each second.
So, it's written like this: 1 N = 1 kg * m/s².
Dyne: This unit is used in a different system called the centimeter-gram-second (CGS) system.
In this system, 1 newton is equal to 100,000 dynes.
Pound-force (lbf): This unit is often used in the imperial system.
Here, 1 pound-force is the force needed to make a one-pound weight speed up by 32.2 feet each second.
Depending on where you are and what you're measuring, you'll use these units to talk about force!
