Lab: Newton's Laws of Motion

What is the average velocity of the car over the first 0.25m? What is the average velocity of the car over the second 0.25m?

0.11 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?

0.33 0.17

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

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

Use what you know about mass and how you use it to calculate force in the following situation.

3rd choice 2nd choice

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

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.

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
