Question

4 What is work and energy?​

Answer 1

Answer:

☞￣ᴥ￣☞

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.

SI unit: joule (J)

In SI base units: 1 kg⋅m2⋅s−2
