1. Open the following page:
http://www.physicslessons.com/phe/inclplane.htm
2. Set the following variables:
Angle of inclination = 25 degrees
Weight = 5.0N
Coeff. of Friction = 0.25
3. Given the above variables, show how to calculate:
- parallel component
- normal force
- force of friction
- necessary force (force to push or pull object up the ramp).
4. Calculate the work done in pushing the object from the bottom of the ramp to the top.
5. Using the same initial settings, how fast would the object be travelling (in m/s) at the bottom of the ramp if it was released from the top of the ramp.
6. Maintain a weight of 5.0N and a coefficient of friction of 0.25, vary the angle of incline from 0.0 degrees to 90 degrees. What happens to parallel component, normal force, force of friction and necessary force and explain why (in detail - a graph would help the explanation).
1) Open the following page:
http://physics.bu.edu/~duffy/java/Spring2.html
2) Does the law of conservation of energy apply here? Explain.
3) How does the initial displacement from the equilibrium position affect the total energy?
4) How does it affect the maximum speed of the block?
5) Where does the block reach its maximum speed?
6) In what form is the energy (how much potential and how much kinetic) at this point?
7) Is there any connection between the direction of the displacement and the direction of the acceleration (the acceleration indicates the direction of the force applied by the spring on the block)?
