Types of Forces in AS-Level Physics At AS level, forces are categorized into different types based on how they act and their effects on objects. Here’s a closer look at key force types, including weight, normal contact force, frictional force, resistive force, and upthrust. Force is the rate of

1.How to describe a wave * Wavelength λ unit:meter m Definition:Distance between two adjacent wavefronts OR Distance between two adjacent points which are oscillating in phase * Frequency f unit:Hertz Hz Definition:Number of oscillation completed per unit time * Wave speed v unit:meter/second m/s * Period
