Product Details
This simulation scaffolds the main concepts of forces and motion through 4 different screens: Net Force and Motion, The Basics of Motion, Friction, and Acceleration. The first screen allows students to see how balanced and unbalanced forces affect the acceleration of a massive cart. The subsequent screens allow students to use a robotic pusher to demonstrate the principle of equal and opposite forces and how applying a force to an object that is already moving can cause it to accelerate in a specific direction.
The final screen, Friction, is a demonstration of how kinetic friction affects objects. It starts with your avatar standing next to a wooden crate and you are given the option of selecting the force that you will be pushing it with (it must be moving for a friction screen to appear). Once you select your desired force, you will observe how kinetic friction causes the crate to accelerate and the resulting acceleration vector displayed on the left side of the screen.
Haptic feedback technology recreates the sense of touch by sending a dedicated output signal from the finger position sensor to piezoelectric actuators embedded in the display. By varying the shape of the actuators, it creates more or less intense friction sensation underneath the finger in real-time offering localized haptic feedback. This makes scroll wheels, sliders and buttons obsolete by allowing users to feel the turn of a knob or the push of a cursor.
