* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
* Acceleration: Acceleration is the rate of change of velocity. If an object is speeding up, it's accelerating.
* Net Force: Net force is the overall force acting on an object after considering all the forces acting on it. It's the vector sum of all the forces.
In simpler terms:
* If you push a box forward (applying a force), it will start to move.
* The harder you push (more force), the faster it will move (greater acceleration).
* If you stop pushing, the box will eventually stop moving because of friction (a force acting against motion).
Therefore, to make an object speed up, you need a net force acting in the direction of motion.
