Lab: Newton's First Law Demonstrations In this activity, you will examine Newton's First Law using tug of war. The instructions are quite specic. so please make sure you read them carefully. This mini-lab will be graded. Each question will be out of 2, plus 2 for the warm-up observations, Simulation Notes The orange reset button J will return all people to the storage and set the cart back to 0 the start o The yellow return button m will return the cart to 0, but keep all the people G t o The green go button .3) starts the simulation o Pressing it while the simulation is running . causes it to pause but keep all of your current settings o If the cart ever reaches the two grey markers on the sides, itwill end the simulation Setu p 1.

Click the orange \"reset\" button on the right 3. Make sure the following options are selected: Values and Speed. - C] Sum of Forces 3 Values [3/ Speed WarmUp Click and drag the different people sizes onto the rope and press \"Got". Record the force they can pull with and the visual observation of what happens in the table below. You may choose either blue or red. they are the same. Person Size Pulling Force (N) Observations No direction needed Situations Follow the instructions for each situation and record your observations Simulation #1 - All Red 1 Reset the simulation o Attach any sized red person a Press Go! 1. Briefly explain why the cart moved. : Situation #2 - Red vs Blue 0 Press the Return button 0 Attach a blue person of equaLsizeto the red person a Press Go!. 2. Briefly note what happened and explain why using Newton's First Law. : Situation #3 - Make 3 Prediction Read the instructions rst, make a prediction, then test to see if you were correct. 0 Press the Reset button Attach a small or medium red person Press Go! Once the cart has started moving, press pause Attach a blue person who is larger than the red person Press Go! 3. Predict: What do you think will happen in this situation? : 4. Try the instructions. Was your prediction correct? Briey explain what happened. : Situation #4 - Prediction Round 2 Read the instructions rst, make a prediction, then test to see if you were correct. o Press the Reset button Attach any sized red person Press Go! Once the cart has started moving, press pause Attach a blue person who is egually sized to the red person Press Go! 5. Predict: What do you think will happen in this situation? : 6. Try the instructions. Was your prediction correct? Explain what happened using Newton's First Law
