3. What is the law of conservation of energy?
4. Define element.
5. What is compound and mixture?​

Answer 1

Answer:

1.The work-energy principle states that an increase in the kinetic energy of a rigid body is caused by an equal amount of positive work done on the body by the resultant force acting on that body. Conversely, a decrease in kinetic energy is caused by an equal amount of negative work done by the resultant force.

2.the ability or capacity to do something or act in a particular way.

3.In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
