Equations of Motion Lab

Equations of Motion Lab

Purpose:

In this activity you will be looking at different relationships that exist for equations of motion.

Part 1:  Motion where Acceleration is zero (Distance and Time)

  1. Open up the program found here.

  2. Lower your car's potential acceleration down to 0 (m/s)/s and pick a speed to use for this entire part of the lab.

  3. Create a data table that will hold the time you are going to be moving and the distance that you cover in that time.

  4. Push down on the gas pedal for any old amount of time you want and record the distance you travel in that time.

  5. Reset your system and push down on the gas for a different amount of time and record your distance.  Repeat this for a total of 5 unique times.  What is the significance of your slope?

  6. Use this program to graph your results.

  7. In your lab book make sure you have your data table, your graph, the equation for you graph and a few sentences telling what is meant by your graph.

Part 2:  Motion where Acceleration is zero (Velocity and Time)

  1. Lower your car's potential acceleration down to 0 (m/s)/s and pick a distance to use for this entire part of the lab. Somewhere between 100 and 200 m should work well.

  2. Create a data table that lists the speeds of your car and the time it takes to move the distance that you have established as your target distance.

  3. Push down on the gas pedal and hold it in place until your car reaches your target distance.  Don't be too concerned about missing your target by a meter or two, but if you are too far off of your target, reset and try again.  Record the speed of the car and the time it took to reach your target.

  4. Reset your system, change the speed and again see how much time is required to reach your target.  Repeat this for a total of 5 unique speeds.

  5. Use this program to graph your results.

  6. In your lab book make sure you have your data table, your graph, the equation for you graph and a few sentences telling what is meant by your graph.  What is the significance of your graph constant?

Part 3:  Motion where Acceleration is non-zero (Velocity and Time)

  1. Raise your car's potential acceleration to some number greater than 0 (m/s)/s.  Make sure that your starting speed is at a value greater than 0 m/s.

  2. Create a data table that lists the final speed of your car and the time that you will be accelerating.

  3. Push down on the gas pedal and hold it in place for some random amount of time. Record the time of your acceleration and the final speed of your car.  Make sure you don't pin the needle of your speedometer or your data will be useless.

  4. Reset your system, change the amount of time for which you are accelerating.  Record the new final speed and time of acceleration.  Repeat this for a total of 5 unique times.

  5. Use this program to graph your results.

  6. In your lab book make sure you have your data table, your graph, the equation for you graph and a few sentences telling what is meant by your graph.  What is the significance of your slope and your y-intercept?

Part 4:  Motion where Acceleration is non-zero (Distance and Time)

  1. Raise your car's potential acceleration to some number greater than 0 (m/s)/s, but set your starting speed to 0 m/s.

  2. Create a data table that lists the distance travelled by your car and the time that you will be accelerating.

  3. Push down on the gas pedal and hold it in place for some random amount of time. Record the time of your acceleration and the distance travelled by your car.  Make sure you don't pin the needle of your speedometer or your data will be useless.

  4. Reset your system, change the amount of time for which you are accelerating.  Record the new distance and time of acceleration.  Repeat this for a total of 5 unique times.

  5. Use this program to graph your results.

  6. In your lab book make sure you have your data table, your graph, the equation for you graph and a few sentences telling what is meant by your graph.  What is the significance of your graph constant?

Part 5:  Motion where Acceleration is non-zero (Distance and Final Speed)

  1. Raise your car's potential acceleration to some number greater than 0 (m/s)/s, but set your starting speed to 0 m/s.

  2. Create a data table that lists the distance travelled by your car and the final speed that your car will obtain.

  3. Push down on the gas pedal and hold it in place until you reach some arbitrary final speed. Record the final speed of the car and the distance travelled by your car.  Make sure you don't pin the needle of your speedometer or your data will be useless.

  4. Reset your system, then accelerate until you hit some new arbitrary final speed.  Record the new distance and final speed.  Repeat this for a total of 5 unique final speeds.

  5. Use this program to graph your results.

  6. In your lab book make sure you have your data table, your graph, the equation for you graph and a few sentences telling what is meant by your graph.  What is the significance of your graph constant?
