# A Study of Kinetic Energy

Kinetic energy is energy that an object or person possesses as a result of movement Mathematically it can be shown as half the objects mass multiplied by its speed squared The kinetic energy of an object is given by the equation Ek 2 Where m represents mass and v represents the speed of the object or person There are many forms of kinetic energy and they are Vibrational The energy resulting from vibrational motion Rotational The energy resulting from rotational motion Translational The energy resulting from motion of one location to another Kinetic energy is a scalar quantity because it is merely a magnitude without a direction Gravitational Potential Energy Ug is energy an object has because of its position in a gravitational field The gravitational potential energy of an object is dependent on two variables - The mass of the object - The height to which the object is raised The higher the object is lifted the greater the gravitational potential energy will be The gravitational potential energy of an object is given by the equation Ug mgh Where Ug is the symbol for gravitational potential energy m represents mass in kilograms g represents the acceleration of gravity in metres per second squared and h represents the height of the object in metres Both Kinetic and Gravitational potential energy are measured in Joules or kg m2s2 using the standard metric system Kinetic energy can be passed from one object to another For example when you play bowling you roll the ball down the lane thus giving it kinetic energy When the bowling ball collides with one of the ten pins it slows down and passes the kinetic energy onto the pins which in turn hits another and passes it on Gravitational potential energy is the energy stored in an object as a result of its vertical position For example the tabletop has zero height so a basketball lying on top of

@Kibin is a lifesaver for my essay right now!!
