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:
Slide6•KE & 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
