Hypothesis: As the angle of incline increases, the force of friction between the object and the surface will also increase. This relationship can be described by the equation Ff = uFn , where Ff is the force of friction, u is the coefficient of friction, and Fn is the normal force. The normal force is given by Fn = mgcosθ , where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s ²), and θ is the angle of incline. Therefore, the force of friction is directly proportional to the normal force, which increases as the angle of incline increases. Materials:  Computer with internet access  PhET Simulation: The Ramp Procedure: After finishing the experiment on the PhET Simulation: The Ramp. First, I selected the mass of the object and the coefficient of friction from the menu. After setting the ramp angle to 0 degrees, I carefully placed the object on the ramp and hit the play button to start its motion. As the object moved, I recorded both the force of friction and the angle of incline. I'm now in the process of repeating these steps for different ramp angles, ranging from 5° to 45°. Each time, I'm adjusting the starting position and documenting the data in a table. It's interesting to observe how the force of friction changes with varying incline angles, and I'm eager to analyze the collected data. Observations:  The force of friction increased as the angle of incline increased.  The angle of incline had a significant effect on the force of friction.  The force of friction was greater for objects with higher masses and higher coefficients of friction.

 The force of friction was greatest when the object was at rest or moving at a constant speed. Results: The following table shows the relationship between the angle of incline and the force of friction for an object of mass 100 kg and coefficient of friction 0.3.

This relationship can be explained by the fact that as
