Object: When an object is moving down a frictionless inclined plane the only force pushing it down is mgSin( θ ); the component of it’s weight. When put into Newton’s second law, F=ma, mgsin( θ )=ma, it can be concluded that gsin( θ )=a. The object of this lab is to prove a=gsin( θ ). Procedure: 1. Gather all blocks and objects to prop the track up with. 2. Measure the width of one of the items and record on data table 3. Prop up the air track 4. Measure the length of the cart by passing it through the photogate and watching the light and looking at the ruler. 5. Move cart back 50 inches and keep it steady 6. Let go of cart and record time said on the timer gate 7. Repeat these steps 9 times Sample Calculations: Σ f=ma mgsin θ =ma gsin θ =a sin θ =h/B V 2 =2V o +2as a=gh/B a=V 2 /2x gh/B=v 2 /2x v 2 =2gxh/B Example: Trial #1
