Physics in Our Everyday Life

Physics In Our Everyday Life

Physics is not something that only knowledgeable scientist think about

because physics coincides with our everyday life. They consist of

energy, kinetic energy, potential energy, conservation of energy,

velocity, acceleration, mass, force, and gravity.

Fist there is energy. You need to go to bed early so you will

have energy in the morning to go to school. Energy gives you the e

ability to do work. Energy is everywhere in nature, sunlight wind,

water, plants, and animals. We use energy everyday. There are two

kinds or energy. There’s kinetic energy and potential energy. There

are many forms of energy… there’s light, chemical, mechanical, heat,

electric, automatic, and sound. All these forms of energy can be

broken down either into kinetic energy or potential energy. The law of

conservation of energy is that energy can neither be created nor

destroyed. The total energy of an object never changes.

Then there’s kinetic energy. There are many types of energy,

but one of the most interesting types of energy is kinetic. Kinetic

energy is the energy of motion. When an object is in motion, even in a

vertical or horizontal motion, it has kinetic energy. There are three

types of kinetic energy; rotational, vibrational, and transnational.

To find kinetic energy in an equation, you will need the mass and

speed of the object. Usually potential energy is turned into kinetic

energy. When a cart is on top of a hill, it is full of potential

energy. As soon as it starts going down the hill it starts gaining

kinetic energy.

After comes potential energy and force. Potential energy can

store energy as the result of its position. Potential energy exists

whenever an object that has, mass a position within a force field. The

most everyday example of this is the position of objects in the

earth’s gravitational field. The potential energy of an object in this

case is given by the relation PE=mgh.

Force is any influence that tends to accelerate to an object.

Force is any type of push or pull. Force can also be measured in

Newton’s. It is mainly when an object is moving. For example when an

object is at rest on the top of a hill, then a man comes and pushes it

with all his strength, the car will move some.

Don’t forget about conservation of energy. The conservation of

energy is the amount of energy changed or transformed with no loss or

gain. The law of conservation of energy is: energy cannot be created

or destroyed. It can be transformed from one form to another, but the

total amount of energy never changes. Energy takes into account the

fact that each atom that makes up matter is a concentrated bundle of

energy.

Then there’s velocity and mass. Velocity is speed in a given

direction. Speed and velocity are used interchangeable in everyday

life. There is one small difference though. Velocity is speed given in

a direction. It is how fast an object goes and in what direction. To

have constant velocity, you must have constant speed and constant

direction. Constant speed means that the motion remains at the same

speed. Constant
