Example when work done is 0
WebExample Problem 1 - Calculating the Work Done on an Object at an Angle A person pulls a sled along a flat snowy surface, dragging it with a rope. The rope makes a 20-degree angle with the ground. WebAns: In this case, the work done on the cycle by the road will be equal to the work done by the stopping or the frictional force on the cycle due to the road. The angle between the stopping force and the displacement is 180 degrees. So, now the work done by the road is-. W = F d cosθ. W = 200 × 10 × cos180.

When a constant force is applied to move an object a distance , the amount of work performed is. The SI unit of force is the Newton, (kg m/s) and the SI unit of distance is a meter (m). The fundamental unit of work is one Newton-meter, or a joule (J).
WebAnswer (1 of 2): Work done W = F . ds, where F is force and ds is elemental displacement. W is zero, 1. When the force F is zero, a uniform motion in a straight line 2. If the displacement ds is zero, even if F is not zero. A force moving an object without being … Web2 days ago · Zero Work: If the direction of the force and the displacement are perpendicular to each other, the total work done by the force on the object is null. For example, when we thrust hard against a wall, the force we are applying on the wall does not work, …
