4. Write differences between friction and gravity |
| Answer» <p>(i) Friction is the force that opposes the sliding motion. Gravity is the natural force exerted between two objects, drawing them toward each other.</p><p>(ii) Gravity always pulls objects. Friction, however, doesn’t pull objects down.</p><p>(iii) Unlike gravity, friction doesn’t rely on a natural force. Instead, friction occurs when something like a machine or individual pulls a sliding object in the opposite direction of another object.</p><p>(iv) Friction always acts parallel to the surface in contact because of the sliding action. Gravity acts perpendicular downwards.</p> | |
