Question

Draw and label a free-body diagram for the Einstein figure in Part One, when it was in motion down the incline.

Now, apply Newton’s 2^nd law to the Einstein figure and derive Equation (2). Be sure to clearly

μk = tan θ−ax / g cosθ (2)

show all of the steps in your derivation.

Transcribed Image Text:### Understanding Friction on an Inclined Plane In this interactive demonstration, we observe a hand holding and tilting a wooden board with a toy figure placed on it. The toy is in motion, sliding down the inclined plane due to gravity. **Video Controls:** - **Replay, Reverse, Play/Pause:** These buttons allow the user to control the video playback. - **Progress Bar:** This indicates the current position in the video and allows navigation by clicking or dragging. - **Pivot Interactives Logo:** This indicates the source of the video, offering interactive educational tools. **Concepts Illustrated:** - **Inclined Plane Physics:** This setup demonstrates basic physics principles such as gravity, normal force, and kinetic friction. - **Frictional Forces:** Observe how the toy slides down, illustrating the concept of friction which opposes the motion. - **Force Components:** The gravitational force acting on the toy can be broken down into components parallel and perpendicular to the plane. ### Key Takeaways - Inclined planes help demonstrate how different forces interact in physics. - The angle of inclination affects the rate of acceleration due to gravity and friction. - Educational tools like Pivot Interactives provide hands-on learning experiences for better comprehension of fundamental physics.
