www does the efficiency of an inclined plane depend on its angle of inclination? /1k If I increase the angle of inclination, the efficiency of the inclined plane would increase since with a higher angle Overview: It unit make the inclined plane more efficient. Sliding a crate up a ramp is usually easier than lifting it straight up. In this activity, you will measure the work done sliding a block up an incline and compare it to the work needed for a vertical lift. The height of the ramp can be adjusted to see how the required applied force changes with the angle of the incline. You will determine which angle of inclination is the most efficient and which is easiest to use. Set up: Figure 6.31 you will set up a wooden plank on one, two, three. and four books and use a spring scale to measure the force needed to slide a wooden block up the ramp. 0 50 0 4 1 .2 = 0. 612 Observations: 0 -67 /9 1. 2 m 1C Mass: Ad: Height (h) Angle of Work Gravitational Efficiency Applied Force (N) inclination ( J ) Potential Energy Eff = W 4 x100% (J) 2 books 1 6 N 3. 680 CM 115 6 (ML 7.470 6 books 11.20 13K 30 /1C Sig figs and units
