1. A force can
a) move a stantionary object
b) change the motion of an object
c) change the shape of an object
2. During a football game, we can clearly observe the effects of a force to the motion of an object.
A Force Can Move a Stationary Object
1. A stationary ball will move when it is kicked.
2. A force is applied to the ball when it is kicked. This force causes the ball to start moving.
3. The ball moves in the same direction as the applied force.
4. The ball will move faster or roll further it we kick harder.
A Force Can Changes the Motion of an Object
1. The direction of the force applied to an object will determine its motion.
2. A moving ball will move faster if a force is applied in the same direction of its motion.
3. On the other hand, a moving ball will move slower if a force is applied in the opposite direction of its motion.
4. Also, a moving ball will change its direction when a force is applied from another direction when a force is applied from another direction of its motion.
5. A force can cause a moving object to stop.
a) For example, when a goalkeeper catches a moving ball with his hands, the ball will stop.
b) The goalkeeper exerts an opposing force on the moving ball by catching it.
A Force Can Change the Shape of an Object
1. A force can cause the shape of an object to change.
2. The changes of the objects when a force is applied may be temporary or permanent depending on the physical characteristic of the object.
3. Elastic objects such as the spring and rubber band only change shape when force is applied to them.
4. When the force is removed, the object returns to its original shape.
5. When force is exerted on a fragile object, the object will be broken apart. The change of shape is permanent.
