## Mechanical energy is ___.

The energy associated with the movement of objects is known as kinetic energy. While kinetic energy can take many forms, it is most commonly associated with the movement of larger objects. Thermal energy, for example, occurs as a result of the movement of atoms or molecules, and hence is a modification of kinetic energy. Kinetic energy, on the other hand, is most often correlated with the movement of larger objects. As a result, an object with zero kinetic energy is one that is not moving. An object’s kinetic energy is measured by both its mass and velocity, with velocity playing a much larger role.

## Which of the following has the greatest kinetic energy

Chemists classify energy into two groups. Kinetic energy is the energy retained by a moving entity. Kinetic energy exists in the earth’s rotation around the sun, in you walking down the street, and in molecules traveling in space.
The kinetic energy of an object is directly proportional to its mass and the square of its velocity: K.E. = 1/2 m v2. The kinetic energy has units of kilograms-meters squared per second squared if the mass is in kilograms and the velocity is in meters per second. Joules (J) are widely used to calculate kinetic energy; one Joule equals 1 kg m2 / s2.
That’s right! Since velocity is squared, the kinetic energy of the running man is far higher than that of the walking man. Take note of the amount of energy the moving car has. It’s no surprise that accidents can do so much harm.

### At 20 ∘c (approximately room temperature) the average velocity of n2 molecules in air is 1050 mph.

We must work in order to cause an object to deform. Whether plucking a guitar string or compressing a car’s shock absorber, a force must be applied over a distance. If the only effect is deformation and no work is converted to thermal, sound, or kinetic energy, then all of the work is initially retained as potential energy in the deformed object.
Consider the oscillation in SHM of a block attached to a spring on a frictionless table. We can describe a potential energy for the spring force because it is a conservative force (as you learned in the chapter on potential energy and conservation of energy). The energy contained in the spring as it is stretched or compressed is referred to as potential energy. The block oscillates in one direction in this case, with the spring force acting parallel to the motion:
The equilibrium state, marked as [latex] x i=0.00,textm, [/latex] when considering the energy stored in a spring, is the position at which the energy stored in the spring is equal to zero. The potential energy contained in the spring is increased when it is extended or compressed by a distance x.
