* Force: This is any interaction that can cause a change in an object's motion. A force can cause an object to speed up, slow down, or change direction. Examples include pushing, pulling, friction, gravity, and magnetic forces.
* Net Force: This is the vector sum of all the forces acting on an object. If the net force is zero, the object's velocity will remain constant (Newton's First Law of Motion). If the net force is not zero, the object's velocity will change.
Let me know if you want more details about how forces affect velocity!
