WebPE = 0.8 × 10 × 0.2 PE = 1.6 J Example 2: A wagon loaded with iron blocks is pushed up an inclined plane to its highest point. The total mass of the wagon is 50 kg and the height of the topmost point from the ground is 5 meters. What is the total potential energy of the wagon at the top? Solution: Given: m = 50 kg g = 10 m/s 2 h = 5 m WebWith an incline that is frictionless and you have a block on it the block's weight is directed strait down but the normal force is perpendicular to the incline so when you add the force vectors you end up with a net force …

WebMay 16, 2024 · Let angle of inclination of the inclined plane is x, then the component of gravitational force along the plane is mgSin(x). So the tension in the string is also mg Sin( x ) along the plane upwards. The component of gravitational force perpendicular to the plane is mg Cos( x ) and normal force balances it. WebDr. W. Pezzaglia Physics 2A Lab, Fall 2012 Page 1 ... the inclined plane, there is a drop in gravitational energy, which is converted into kinetic energy. For a sliding object, all of this energy goes into its linear motion. For a rolling body, the energy ...
