S: 2m 10.01.14 Work Stations N 10,000 Calculate work: We will contrast situation of work and no work by creating diagrams of different situations where work or no work may be done. S: Calculate work: Write the equation Plug in the numbers for force and distance Multiply Label your answer with the correct unit 10,000 N 2m

P: Describe how we know if work is being done.

A&C: At each station: Record the station number from the direction card at your station. Draw the situation. Label the arrows with force and distance. Explain if work is being done or not!

E: Use a half page to contrast if work or no work is being done in each picture. Describe both the force and the distance for each situation. Remember these pictures aren’t in your journal so you must describe with words!

S- Be sure to justify your answer! 10.02.14 Ramp Lab We will determine how ramps affect the amount of force by completing a lab S- Be sure to justify your answer! 1 D

P Title: Force and Ramps Purpose: How will the angle of a ramp effect the amount of force needed to move the object? Materials: ramp, object, spring scale, protractor Hypothesis: If we increase the angle of the ramp then the amount of force needed to move the object will ___________ because…

P Procedures: At each of the angles, use the spring scale to measure the amount of force needed to move it up the ramp. Angle Force 30 degrees 60 degrees 90 degrees

A Graphing our independent and dependent variables. Independent variable (X axis ): Dependent variable (Y axis): Constant variable: C What is the relationship between the angle of the ramp and the amount of force needed to move the object? Use your graph to justify your answer.
