1.	Classify the following as contact and non-contact forces : 1. A horse pulling a cart 2. A magnet attracting a piece of iron. 3. A freely falling stone. 4. A boy shooting an arrow from a bow. 5. Tides in the sea. 6. A speeding car stops when an engine is switched off. 7. Two negatively charged ball repelling each other. 8. Crushing paper into paper ball.
Answer» 1. A horse pulling a cart → Contact force. 2. A magnet attracting a piece of iron → Non contact force. 3. A freely falling body → Non-contact force. 4. A boy shooting an arrow from a bow → Contact force. 5. Tides in the sea → Non-contact force. 6. A speeding car stops when an engine is switched off → Contact force. 7. Two negatively charged ball repelling each other → Non-contact force. 8. Crushing paper into paper ball → Contact force.
