However, it's important to clarify that:
* Force can also slow down an object - This is called deceleration or negative acceleration.
* Force can change the direction of an object's motion - This is called a change in velocity.
To be more precise, we can say:
* A force that causes an object to speed up is called a net force in the direction of motion**. This means that the force acting on the object in the direction of its motion is greater than the force acting against its motion.
Think of it like this:
* Pushing a box: You apply force to the box to make it move faster.
* Wind pushing a sail: The wind applies force to the sail to make the boat move faster.
