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. Theres kinetic energy and potential energy. There
are many forms of energy theres 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 theres 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
earths 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
Newtons. 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.
Dont 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 theres 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 direction is that the motion is in a straight line. If
