What is Force?
When you get to school, you open your locker door and lift your books into your arms. You are late, so you have to run to class, slowing down when you get closer to the door. A typical scene in the day of a student, right? Although you might not know about force yet, in all the actions mentioned here, force is letting you complete them!
Force is an interaction between objects that causes them to change motion. So, when you opened your locker door, your hand applied a force to the door, causing it to change its motion. We measure force in newtons (N), the scientific unit for measuring weight. One newton is equal to about 0.22 pounds. So, a girl weighing only 100 lbs. would be equal to approximately 445 newtons, or her force due to gravity (Fg). Now that we know some basics, let's look at how we use the formula for force.
Force Formula
The formula for force states that force is equal to mass multiplied by acceleration. So, if you know mass and acceleration, just multiply them together and now you know the force! The units for acceleration are meters per second squared ( m/s2), and the units for mass are kilograms (kg).
