What is friction?

1. Friction is a force that opposes motion.

2. Friction exists when two surfaces are in contact against each other.

3. The direction of the frictional force is always opposite to the direction of movement of an object.

4. For example, a ball rolling on floor will eventually stop.

5. This happens because there is friction between the surfaces of the ball and the floor.

6. The friction opposes the motion of the ball, causing it to slow down an stop.

Apakah geseran?

1. Geseran ialah daya yang menentang pergerakan.

2. Geseran wujud apabila dua permukaan bersentuhan antara satu sama lain.

3. Arah daya geseran sentiasa bertentangan dengan arah gerakan objek.

4. Contohnya, bola yang sedang bergolek di atas lantai akhirnya akan berhenti.

5. Ini berlaku kerana wujud geseran antara permukaan bola dan lantai.

6. Geseran menentang pergerakan bola, menyebabkan bola bergerak lebih perlahan dan akhirnya berhenti.
