Inclined Plane Lab：斜面的实验室.doc

Inclined Plane Lab Name: _1) Problem: How does an inclined plane use less effort force?2) Research: An inclined plane is a sloping, slanted surface used to raise objects and includes ramps, wedges, & screws. Work= force X distance.3) Hypothesis: If the distance of an inclined plane is increased, then the effort force required to move the weight will _.If the height of an inclined plane is increased, then the effort force required to move the weight will _.4) Experiment: Use the procedures at your lab station and complete the data table below.Data Table 1: Calculating work along an inclined planeLab Station #Distance (cm)Effort Force(N)Lab StationHeight (cm)Effort Force(N) *Without inclined plane *Without inclined plane#1A#2B#3C#4D5) Results: Based on your data table results, answer the following questions-a) How does the amount of effort force used to pick the car (weight) straight-up off the ground compare to pulling the car (weight) up one of the inclined planes? _ _b) How does the amount of effort force used compare from station #1 to station #4? _ c) How does the amount of effort force used compare from station A to station D? _6) Conclusion: Does your data support your hypothesis? _7) Reflection: Explain what would be the best type of ramp to build onto your home if you needed a wheelchair ramp.

If it does not read 0, adjust it until it does.2) Using the meter stick measure the amount of force required to move the weight (car) 10cm. without using an inclined plane. Attach the spring scale to the car & lift it straight up off the ground 10cm. into the air & record in the data table the effort force in Newtons and the distance as 10cm.3) Take your car & meter stick to your first station. Each group will visit each station one time. Make sure you record your data in the correct location of your data table.4) Measure the distance of the inclined plane at your lab station by laying the meter stick down on it & record the length in centimeters in the data table.5) Place the back wheels of your car at the bottom of the inclined plane & slowly pull the car up the inclined plane with the use of the spring scale. 6) Read the effort force in Newtons as you pull your car up the incline & record the effort force in the data table. Make sure you record the effort force using decimals when needed.7) Repeat steps 1-6 for each station. Make sure you take your car & meter stick with you to each new station. You should visit a station labeled #1, #2, #3, & #4.Inclined Plane Lab Procedure Steps:1) Make sure your spring scale reads “0” N by laying it flat on the table.
