Lab Newton's Laws of Motion Assignment Reflect on the Lab correctly answered

Lab Newton's Laws of Motion Assignment Reflect on the LabThroughout the reflection, make sure you have a copy of the Student Guide and your data tables. Use the drop-down menus to complete the statements. In Part I of this experiment, the mass of the car was intentionally manipulated. This was the independent variable. The dependent variable measured was the . In Part II of this experiment, the mass of the car angle of the track was intentionally manipulated. This was the independent variable. The dependent variable measured was the . 1. the 2nd choice 2. the 1st choice 3. the 2nd choice 4. the 1st choice Different measurements are expressed in different units. Choose the correct SI units for the following types of measurement. The SI units for measuring the velocity of the car: The SI units for measuring the acceleration of the car: The SI units for measuring force: The SI units for measuring mass: 2nd 3rd 4th 1st What is the average velocity of the car over the first 0.25m? m/s What is the average velocity of the car over the second 0.25m? m/s 1. 0.11 2. 0.28 The acceleration of the car with the data in the table above would be If the applied force were cut in half, what do you predict the acceleration would be? 1. 0.33 2. 0.17 Which arrow represents the force of gravity acting upon the car?Which arrow represents the normal force on the car?Which arrow represents the applied force on the car when the driver steps on the gas pedal? B A C Use what you know about mass and how you use it to calculate force in the following situation the 3rd choice the 2nd choice The average time that it takes for the car to travel the first 0.25 m is The average time to travel just between 0.25 m and 0.50 m is Given the time taken to travel the second 0.25 m section, the velocity would be 2.23 0.9 0.28 If you know the force applied to an object and measure its acceleration, which equation would you use to calculate the object's mass? m=F/a The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be The mass of 3 washers, when converted to kg, is The applied force of 3 washers will increase the applied force on the car to 10 0.0147 0.147 Consider the relationship of the variables in Newton's second law. In a drag car race, the force applied to the car is doubled by the driver stepping on the gas pedal. double remain uncharged increase
