What are the various energy transformations that occur when you are riding a bicycle?
When you ride a bicycle, several energy transformations take place: Chemical energy ---> Mechanical energy:The chemical energy stored in your muscl...
The potential energy of a freely falling object decreases progressively. Does this violate the law of conservation of energy? Why?
No, it does not violate the law of conservation of energy. Explanation: As the object falls, its potential energy decreases because its height decrea...
A mass of 10 kg is at a point A on a table. It is moved to a point B. If the line joining A and B is horizontal, what is the work done on the object by the gravitational force? Explain your answer.
The work done by the gravitational force is zero. Explanation: Work done by gravity depends only on the vertical movement.Here, the object moves horiz...
Certain force acting on a 20 kg mass changes its velocity from 5 m/s to 2 m/s. Calculate the work done by the force.
To find the work done, we use the formula for change in kinetic energy: Work done = ½ m (v₂² – v₁²) Here:m = 20 kgv₁ = 5 m/sv₂ = 2 m/s Now,Work done =...
