Newton's Second Law of Motion
The relationship between force, mass, and acceleration is described by Newton's Second Law of Motion:
* Force (F) = Mass (m) x Acceleration (a)
This equation tells us:
* Direct Proportionality: Acceleration is directly proportional to the net force applied. This means that if you increase the force, you increase the acceleration. Double the force, and you double the acceleration.
* Inverse Proportionality: Acceleration is inversely proportional to the mass of the object. This means that if you increase the mass, you decrease the acceleration. Double the mass, and you halve the acceleration.
Examples
* Pushing a Cart: If you push a cart with a small force, it will accelerate slowly. If you push it with a larger force, it will accelerate faster.
* Throwing a Ball: A heavier ball will accelerate slower when thrown with the same force as a lighter ball.
Key Points
* Net Force: The acceleration depends on the *net force* acting on the object. This is the vector sum of all forces acting on the object. If forces are balanced, the net force is zero, and there's no acceleration.
* Direction: Force and acceleration are vectors, meaning they have both magnitude and direction. The direction of the acceleration is the same as the direction of the net force.
