Motion
| Term | Definition |
|---|---|
| Pendulum | A weight on a string that hangs from a single point. It swings and creates a pattern of motion! |
| Motion | The process of an object moving or being moved. |
| Pattern | A series of repeating events. |
| Pattern of Motion | When a moving object makes the same pattern again and again. |
| Outcome | The results of tests after we make predictions. |
| Friction | The force resisting motion. It slows things down. |
| Sandpaper | A rough material made from pieces of sand glued to paper. Rubbing it on surfaces causes a lot of friction. |
| Why does one car move down the ramp faster than the other even though they are the same and released at the same time? | One side of the ramp is rougher than the other. The rougher side of the ramp causes more friction, which slows things down. |
| Why is increasing friction a good thing when it comes to car tires? | Although we want cars to be able to move quickly and smoothly down a road, we also want cars to be safe and not to slide off the road! Tire treads are carefully engineered to grip the road so the car can steer and turn safely |
| What are some examples of very fast motions? What about extremely slow motions? | Fast motion could include the flapping of a bee's wings, a cheetah running, an airplane flying or a speaker vibrating. Some really slow motions could be a plant growing, a glacier sliding or a snail moving. No matter how slow motion is, it's still motion! |
