* Speed: A net force (the overall force acting on an object) causes a change in an object's speed. This means:
* Acceleration: A force in the *same direction* as the object's motion causes it to speed up.
* Deceleration: A force in the *opposite direction* to the object's motion causes it to slow down.
* Direction: Any force acting at an angle to the object's motion will change its direction. This means the object will move along a curved path.
In Summary:
* Force in the same direction as motion: Changes speed (accelerates)
* Force in the opposite direction as motion: Changes speed (decelerates)
* Force at an angle to motion: Changes direction
Important Note: If the forces acting on an object are balanced (net force is zero), the object's speed and direction will remain constant. This is known as Newton's First Law of Motion (the Law of Inertia).
