Slide1Energy

Slide2A Few Types of Energy1. Mechanical 2. Chemical 3. Thermal (Heat) 4. Solar 5. Electrical 6. Nuclear 7. Sound 8. Light

Slide3Energy is the ability to do workThere are many forms of ENERGY But they all fit into 2 Main Categories 1. Kinetic 2. Potential

Slide4Kinetic EnergyKE = ½  *  mass  *  speed ² Kinetic energy is the energy an object  has because of its motion

Slide5Kinetic Energy        KE = mv²                    2 KE = kinetic energy ( J ) M = mass ( kg ) V 2  =  velocity squared (m/s)  2 Also written as:

Slide6KE & Mass  are  directly proportional If the  MASS  is   DOUBLED , The  KE  is  DOUBLED. • KE & V 2   are  exponentially  proportional If  V 2   -  Doubles ,   KE Quadruples .  (   2 2  = 4  ) If  V 2  -Triples   ,  KE   =  ( 3 2  = 9 ) If  V 2-  Quadruples  , KE = ? KE cont.

Slide7Gravitational P EGPE = m  *  g  *  h GPE    =  F g  * h Gravitational potential energy depends on the weight of the body (mass and g) and its separation from Earth GPE = gravitational potential energy, J m = mass, kg g = accleration due to gravity, m/s 2 h = height above reference level, m

Slide8GPE cont.GPE = m  *  g  *  h GPE    =  F g  * h What formula is  (m x g)  referencing? __________ Remember :    F g   = ____ Therefore  GPE is _____x _____ GPE = gravitational potential energy, J m = mass, kg g = acceleration due to gravity, m/s 2 h = height above reference level, m

Slide9Mechanical Energy(ME) Energy which is possessed by an object due to its   motion  OR its  stored energy ME= KE + PE           and ME = KE + GPE + EPE
