How can you tell kinetic energey and potential energy apart?
Since the moving object can do work, it has energy. The energy of motion is called kinetic energy. Potential Energy Unlike kinetic energy, potential energy is stored energy (ex: a kid is getting ready to take off on a swing). Energy that is stored and is ready to do work is called potential energy. This type of energy has the potential to do work.
How does potential energy become kinetic energy?
The property of body decides as to what kind of energy is contained in it. Potential energy changes into kinetic energy when an object moves. Unlike the potential energy, the kinetic energy can be transferred from one body to another body by the process of collision.

What Is Kinetic Energy?
Let's first explore kinetic energy. Kinetic energy of an object is the energy it contains due to movement. If an object is at rest, it doesn't have kinetic energy. If it's moving, then it has kinetic energy. It's pretty simple!
Why is kinetic energy needed?
Likewise, kinetic energy is needed in order to store potential energy in any system. For example, people use potential energy in food to contract muscles that are needed to ride a bike.
How does kinetic energy work on a bike?
If the person rides the bike to the top of a hill, the kinetic energy of motion is then converted into potential energy stored in the bike at the top of the hill.
What are the two categories of energy?
While there are different forms of energy, all the different forms can be put into two categories. One category would be kinetic energy. That's energy of motion. The other category is potential energy. That's energy stored in an object due to its position. You must c C reate an account to continue watching.
What is the energy that moves cars down the road?
Energy is what moves cars down the road. Energy gets things done. Energy warms the surface of our planet and blows the wind through our hair. Energy contracts muscles and transmits signals within our brain. Energy illuminates the lights in our homes and moves cars down the road. Energy is usually defined as the ability to do work.
What is energy in science?
Energy is usually defined as the ability to do work. Scientists have learned how to change energy from one form into another to make our lives more comfortable. Energy exists in different forms, such as heat, motion, light, chemical, and sound.
Where is potential energy stored?
Work is done when a force moves an object some distance to a new position. In other words, potential energy is stored in a system when something is moved from its natural resting state. Let's look at an example of potential energy.
What is potential energy?
Potential energy (PE) is stored energy due to position or state. a raised hammer has PE due to gravity. fuel and explosives have Chemical PE. a coiled spring or a drawn bow also have PE due to their state.

How does a spring convert potential energy into kinetic energy?
Considering the spring, like elastic rubber, we can physically pull or push it to convert its elastic potential energy into kinetic energy. The more force we apply to it, the more its potential energy is stored, and the more conversion to kinetic energy happens when we let it go.
What energy does a flashlight use?
Like the battery, when we turn the flashlight, its chemical potential energy is converted into another form of kinetic energy known as light energy. Note that here the flashlight not only lights up but also gets heat up. That means the generation of heat energy occurs along with light energy from its chemical potential energy.

The potential energy of particles is the leading cause of the exothermic chemical reaction. When the internal particles such as electrons and protons transition from having higher potential energy to lower potential energy, the conversion of their potential energy into heat energy occurs. The energy conversion leads to breaking existing chemical bonds and forming new bonds in the exothermic reaction.

What is kinetic energy?
Kinetic energy () is a physical *observable*, which means that you can actually measure it in terms of the three classical physical observables: length, mass, and time. depends only on the mass of an object and its velocit. The direct answer is that it happens through Newton’s second law.
How does a gravitational force affect the speed of a body?
Under influence of a gravitational force only a body increases its speed while decreasing the distance from the gravitational field source which means decrease of the gravitational potential energy which is converted into kinetic energy . In a harmonic oscillator like the pendulum both the kinetic energy and potential energy oscillate while the total energy stays constant if there is no friction.

Why does a mass lose energy?
As a mass falls freely through a gravitational field, it loses energy, due to the reducing light speed. At the same time it gains momentum towards the ground, due to its rate of increase in speed relative to the speed of light towards the ground (It's speed is constant but the speed of light is reducing).

Potential Energy and Kinetic Energy
- A hammer: 1. when raised up has potentialenergy (the energy of position or state) 2. when falling down has kineticenergy (the energy of motion)
Gravitational Potential Energy
- When the PE is due to an objects height then: PE due to gravity = m g h Where: 1. m is the objects mass (kg) 2. g is the "gravitational field strength" of 9.8 m/s2near the Earth's surface 3. h is height (m)
Kinetic Energy
- The formula is: KE = ½ m v2 Where 1. m is the object's mass (kg) 2. v is the object's speed (m/s) Let's double the speed! Double the speed and the KE increases by fourtimes. Very important to know
from Pe to Ke
- When falling, an object's PE due to gravity converts into KE and also heatdue to air resistance. Let's drop something!
Summary
- Energy is the ability to do work
