Solve this:
(1) a. Define kinetic energy
b. Give two example from your daily life where you can see kinetic energy is doing work.
c. The kinetic energy of an object of mass m, moving with a velocity of 5ms-1 is 25 J. What will be its kinetic energy if its velocity is double ?
(2) Write any one difference between annelids and arthropoda giving one example of each.
Dear Student ,
Kinetic Energy
Kinetic energy is the energy associated with the movement of objects. Although there are many forms of kinetic energy, this type of energy is often associated with the movement of larger objects. For example, thermal energy exists because of the movement of atoms or molecules, thus thermal energy is a variation of kinetic energy. However, most of the time, kinetic energy refers to the energy associated with the movement of larger objects. Therefore, if an object is not moving, it is said to have zero kinetic energy. The kinetic energy of an object depends on both its mass and velocity, with its velocity playing a much greater role
Example:
1)An asteroid falling to earth at incredible speeds has an enormous amount of kinetic energy.
2)A river flowing at a certain speed possesses kinetic energy because the water has a certain mass and it also has velocity.
Kindly ask different question in different posts .
