* Faster: A force applied in the same direction as an object's motion will make it move faster. Think about pushing a swing - the harder you push (the greater the force), the faster the swing goes.
* Slower: A force applied in the opposite direction to an object's motion will make it move slower. Imagine braking your bicycle - you apply a force to slow the wheels down.
* Change Direction: A force applied at an angle to the object's motion will change its direction. Think of throwing a ball - the force of your throw changes the direction of the ball's motion.
In summary:
* Forces cause acceleration. Acceleration can be an increase in speed, a decrease in speed (deceleration), or a change in direction.
* Newton's Second Law of Motion describes this relationship: Force = Mass x Acceleration
So, forces are the key drivers of an object's motion and how it changes.
