Newton`s Law Concept Test
... When the fly hit the truck, it exerted a force on the truck (only for a fraction of a second). So, in this time period, the truck accelerated (backward) up to some speed. After the fly was squashed, it no longer exerted a force, and the truck simply continued moving at constant speed. Follow-up: Wha ...

Newton`s Second Law of Motion
... the force just change the velocity? Also, what does the mass of the cart have to do with how the motion changes? We know that it takes a much harder push to get a heavy cart moving than a lighter one. A Force Sensor and an Accelerometer will let you measure the force on a cart simultaneously with th ...

Chapter 5 Work and Energy conclusion
... Chapter 6 is about the COLLISION of TWO masses. To understand the interaction, both masses must be considered. Newton's 3rd Law plays a very important part. Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) mass ...
