Frequently Asked Questions
What is Newton's Second Law?
Newton's Second Law states that force equals mass times acceleration (F = ma). It describes how force causes acceleration.
What units are used for force?
Force is measured in Newtons (N) in the SI system. 1 Newton = 1 kg⋅m/s². Other units include pounds-force (lbf).
Can force be negative?
Yes, negative force indicates the force acts in the opposite direction to the chosen positive direction.
What's the difference between mass and weight?
Mass is the amount of matter (kg), while weight is the gravitational force on that mass (N = mg).
How do I calculate net force?
Net force is the vector sum of all forces acting on an object. Use F_net = ma for the resultant acceleration.
