Check what you remember
Read the wording for your board, then hide it and explain Newton's second law in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
F = m × a, where acceleration is directly proportional to the resultant force when mass is constant and inversely proportional to mass when force is constant.
F = m × a, where mass is the constant that links force in newtons to acceleration in m/s².
The word equation for this is resultant force = mass × acceleration.
