Motion and Friction Web quest
Introduction: Forces are continuously acting on objects all the time, and can cause them to move or prevent them from moving. Additionally, moving things behave in predictable ways.
Newton’s Three Laws with a bicycle: Moving objects follow recognizable patterns. Sir Isaac Newton described and quantified these patterns. Watch from my website and answer the following questions.
- What is the law of inertia? How does your bike have inertia?
- Describe the relationship between force, acceleration, and mass. How does this relate to your bike?
- Why do bicycles move forward?
Balanced and Unbalanced Forces: So that actually gets objects moving? Find out more in this video about balanced and unbalanced forces. Watch from my website and answer the following questions.
- What are objects doing if they are not accelerating?
- What are some balanced forces acting on the horse? What makes them balanced?
- What does acceleration mean? How does it happen?
Types of Friction: Friction often acts in opposition to driving forces and moving objects in general. In this video, you will learn more about the different kinds of friction, and some ways engineers reduce friction. Watch from my website and answer the following questions.
- Fill in the Table with descriptions of the different kinds of friction.
Static Friction / Sliding Friction / Rolling Friction / Fluid Friction
- What are some ways engineers reduce friction?
How does Work… work?:When forces cause objects to change their position, work has been done! In this video you will learn more about work, how it is measured, and much work incandescent light bulbs require to glow. Watch
from my website and answer the following questions.
- What is the difference between positive work and negative work?
- What is work? What is power? How are they measured?
- What is horsepower?
Conclusion: What have you learned about motion and friction?
