Can you use an accelerometer to measure force? Accelerometers work by detecting forces. We look at the force acting on a small mass, divide it by the object’s mass, and calculate the force per unit mass. The electronic accelerometer is well suited for recording these forces. Can an accelerometer measure force? An accelerometer is an […]

What are the two rules of refraction? The two laws followed by a beam of light traversing through two media are: The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of […]
