[Q3] FRICTION AND GRAVITY
Notes on Friction and Gravity BY: Pj Miana Friction: 1. Definition: Friction is a force that occurs when two surfaces rub against each other. 2. Examples: - Sliding down a slide at the playground. - Dragging a toy car across the floor. 3. Nature of Friction: - Friction can be helpful or challenging, depending on the situation. - Smooth surfaces (like ice) have low friction, making objects slide easily. - Rough surfaces (like sandpaper) have high friction, making it harder for objects to slide. 4. Role of Friction: - Slows down or stops moving objects. - Can be useful, like when using brakes on a bicycle. - Influences the ease of sliding and movement. Gravity: 1. Definition: Gravity is a force that pulls objects towards each other, especially towards the center of the Earth. 2. Exampl...
