Understanding Force in Physics
Force is a vector quantity that causes an object to accelerate. According to Newton's Second Law, Force = Mass × Acceleration (F = ma).
Common Forces
- Gravity: 9.8 m/s² on Earth
- Friction: Opposes motion
- Normal force: Perpendicular to surface
- Tension: Pulling force via rope
Common questions
What is Newton's Second Law?
Force equals mass times acceleration (F = ma). When a force acts on an object, it causes the object to accelerate.
What is the unit of force?
The SI unit of force is the Newton (N), which equals 1 kg⋅m/s².
How do I calculate force?
Multiply mass (in kg) by acceleration (in m/s²). For example, a 10 kg object accelerating at 5 m/s² experiences a force of 50 N.
