Consider a ball at rest in the middle of a toy wagon. When the wagon is pulled forward, the ball rolls against the back of the wagon. Interpret this observation in terms of Newton’s first law.
Solution 11E Introduction The ball which is kept inside a toy wagon will move towards the backside of the wagon. But initially the ball and wagon were at rest. So, this can be explained by using Newton’s 1st law of motion very clearly. Step 1 Representation of toy wagon and ball Initially the toy wagon was at rest and the ball inside too. It is represented in figure 1. When the toy wagon moves forward, the ball will move backward and it is shown in figure 2.
