1. moving objects under strong strong is just mg. 1. an object moves down to the free 2. mobile object the rache kathai 2. moving objects under strong strong strong N by N mg with perpendicular to the direction of movement at all times. 1. tilt the floor to slide objects on the floor. 2. bend Rails to slide on slippery objects. Objects are only done with mg N. Mg strength not from the work and the work of resistance. From there the value N = voltage 0. , There is no work and the work of resistance. 3. moving objects under strong tension T with mg by tension T perpendicular to the direction of movement at all times. 1. a circular object moving in the vertical Swing the pendulum clock object. Mg strength not from the , from T = 0. Does not have employment and resistance. 4. moving objects under strong spring force F to mg only. 1. the object drop down area are spring bump. 2. use the spring bouncing objects in vertical The force mg and from the force F is not counted as work and resistance. Does not have employment and resistance. 5. moving objects under tension spring, N and mg F only. 1. tilt the floor to slide down the scale of objects, textures, bump spring address the lower part. 2. the object is to flick from a spring on the floor tilt slide. 3. the object is to flick from a spring on the floor tilt slide. The force mg and from F not work and resistance. Work from the N = 0 Consider setting the equation E = E + E + E in various conditions. 6. the Projectile Motion objects from (1) to (2) (2) Are high (1) is the area of triangle equation h that? (1) Dor (2) 0 + mgh = 0 + mv2 mu2.?.? Later, down on the floor object. the lubricant from the arc (1) Dor Dor (2) (3) Unable to set the equation E = E if E + + E = E + E. 8. tie a rope to an object., circular motion in vertical. Unable to set the equation E = E if E + + E = E + E. 9. an object falling from the point m is higher than the position of balance khongsopring h1. When to position (2) an object with V2 speed bump the wrinkles in the spring. Most h2 v3 = 0 if k is invalid value for fee setup spring can set the equation that. E + E = E + E = E + E Mg (h1 + h2 ) + 0 = mgh2 + ? mv2 = ? kh22 + 0 10. the object is on the ground floor the pressure angle q skew an object, spring balance and shorten S1 stress let the fingers when the spring (3) away from the horizontal balance S2 v2 to v3 if speed is the speed of an object when it is horizontal balance equation that can be.E + E = E + E = E + E ? kS21 + 0 = mgS1 sinq + ? mv22 = mg (S1 + S2 ) sinq + ? mv33
