Variables
What you change
- Surface Smoothness
What you measure
- Friction Coefficient
What you keep constant
- Sliding Object
- Inclination Angle
- Sliding Distance
Equations
d = Distance (0.5 m)
t = Time (s)
V = Velocity (\frac{m}{s})
G = Gravity (\frac{m}{s^2})
Θ = Inclination Angle (20)
μ = Friction Coefficient
μ = \frac{d*g*sin(Θ)-\frac{1}{2}*v^2}{d*g*cos(Θ)}
