    Question

    If a force of 20 N is applied to push a 4 kg object,

    what is the acceleration produced?  
    A 2 m/s² Correct Answer Incorrect Answer
    B 4 m/s² Correct Answer Incorrect Answer
    C 5 m/s² Correct Answer Incorrect Answer
    D 8 m/s² Correct Answer Incorrect Answer

    Solution

    Using Newton's Second Law: F = ma a = F/m = 20 / 4 = 5 m/s²   This show how force changes motion.   This law is crucial for calculating effects of force on mass.
