**Kinetic**and Potential

**Energy**.

**Kinetic energy**is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v

^{2}. If the mass has units of kilograms and the velocity of meters per second, the

**kinetic energy**has units of kilograms-meters squared per second squared.

Then, how do you calculate kinetic energy?

In classical mechanics, **kinetic energy** (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the **kinetic energy** is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s^{2}.

Also, how does kinetic energy work? **Kinetic energy is** the **energy** an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to **do work**. After **work** has been done, **energy** has been transferred to the object, and the object will be moving with a new constant speed.

Consequently, what is the symbol for kinetic energy?

The sum of **kinetic** and potential **energy** in the system remains constant, ignoring losses to friction. Common **symbols**. KE, E_{k}, or T. SI unit. joule (J)

What are 5 kinetic energy examples?

When you let go of that ball and let it fall, the potential **energy** converts into **kinetic energy**, or the **energy** associated with motion. There are **five** types of **kinetic energy**: radiant, thermal, sound, electrical and mechanical. Let's explore several **kinetic energy examples** to better illustrate these various forms.
