* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Force is also a vector quantity. It's a push or pull that can change an object's motion.
* Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
In simpler terms:
* To increase speed: Apply a force in the direction of motion.
* To decrease speed: Apply a force in the opposite direction of motion.
* To change direction: Apply a force perpendicular to the direction of motion.
Examples:
* Pushing a car: You apply a force to increase its speed.
* Braking a car: You apply a force to decrease its speed.
* Turning a car: You apply a force to change its direction.
Important Note: The amount of force needed to change the velocity of an object depends on its mass. A more massive object will require a greater force to change its velocity than a less massive object.
