Newton's Laws of Motion Data Table 1. Net Force and Newton's Laws Scenario Net Force Net Force Explanation Newton's Law Law Explanation A book sitting on a table A puck sliding across frictionless ice A child sitting on a merry-go-round turning at a constant speed A person leaning against a wall A rock falling at constant terminal velocity A car driving around a curve at a constant speed of 40 mph A person pushing a box across a frictionless surface A soccer ball placed on the grass Air inside and outside of an inflated balloon Photo 1. Newton's Law Sketch Photo 2. Newton's Law Sketch Photo 3. Newton's Law Sketch Postlab Questions: 1. Define velocity and acceleration. Explain how acceleration can be used to interpret the velocity of an object. 2. Assuming a frictionless surface, explain how Newton's three laws of motion are in action as an air hockey puck slides across the table and then hits the side of the table wall
