Vocabulary : acceleration, force, friction, mass, newton, Newton’s first law, Newton’s second law, Newton’s third law, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo .) 1. Imagine a horse pulling a cart. What would happen to the speed of the cart if several bags of cement were added to the cart? Name: Brittany Caracheo Date:
2. Suppose several more horses were hitched up to the same cart. How would this affect the speed of the cart?
Gizmo Warm-up The Fan Cart Physics Gizmo shows a common teaching tool called a fan cart. Place fan A on the cart and turn it on by clicking the ON/OFF button below. 1. Look at the blue lines coming from the fan. In which direction is the air pushed?
2. Press Play ( ) and observe the cart. In which direction does the cart move?
3. The velocity ( v ) of the cart is its speed and direction. Click Reset ( ). Select the BAR CHART tab, and click Play . Does the velocity change or stay the same? A change in velocity is called acceleration ( a ) Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved Velocity changes
