INITIAL VELOCITY | The beginning or starting velocity of an object before there is any change in its velocity ( acceleration or deceleration). |
INTERNAL ENERGY | The total energy of a system or object, including its potential energy and its kinetic energy |
JOULE | The Si unit of work and energy |
ONE JOULE | equals the force of one newton exerted trhough a distance of one meter. 1 J=1Nm |
ELECTRICAL ENERGY IS EQUIVALENT | to work done in moving a charge, so the joule can also be used to measure electrical energy; 1J = 1VC |
KILOGRAM | The Si unit of mass equal to 1,000 grams |
KINETIC ENERGY | The energy that an object possessess because of its motion |
KINETIC ENERGY FORMULA | KE = 1/2 mv2 |
MAGNITUDE | The size of a vector quantity, ignoring its direction |
