Contact Forces – Applied Force
Learning Objectives
- Understand the concept of contact forces, including applied forces and friction.
- Identify examples of applied forces in everyday situations, such as opening a door or pushing a bike.
- Explain how applied force is used in sports, like lifting weights or playing baseball.
- Analyze the role of applied force in overcoming other forces, such as gravity, to create movement.
Introduction and Hook
Direct Instruction
Explain how applied force is used in sports, like lifting weights or playing baseball. Use examples to illustrate how applied force overcomes other forces, such as gravity.
Introduce the video 'Forces and Motion – Magnitude and Direction' to help students understand how the size and direction of forces influence speed and trajectory.
Guided Exploration
Engage students in a discussion about the role of applied force in overcoming gravity. Use examples like a weightlifter lifting a barbell.
Watch the video 'Forces in Action on the Football Field – Quiz Edition' to explore how forces affect the movement of a soccer ball. This video includes a quiz to reinforce understanding.
Hands-On Activity
Conduct the 'Paper Airplane Challenge' where students design and test paper airplanes to understand aerodynamics and applied force.
Independent Practice
Assign the 'Average Speed' worksheet where students calculate average speed, distance, or time using real-world scenarios.
Check for Understanding
Discuss the results of the hands-on activities and worksheets with students to ensure they understand the concepts of applied force and motion.
Review and Reflection
Encourage students to reflect on how applied forces are present in their daily lives and how they interact with other forces.
Assessment and Extension
Use the 'Applied Force and Motion' assessment to evaluate students' understanding of how applied force changes an object's velocity.
