Motion, Force & Energy Chapter 5.1 Pages 140-145
EnergyEnergy is the ability to do Work or cause a change –Measured in Joules, like Work
Kinetic Energy is the energy of motionKinetic Energy is the energy of motion All moving objects have Kinetic Energy (KE ) What determines an object’s KE? –MassVelocity –Mass & Velocity determine the KE of an object.
Potential Energy is stored energyPotential Energy (PE ) is stored energy –It has the potential or “possibility” to do work Gravitational PEGravitational PE is energy that depends on height Elastic PEElastic PE is for objects that can be stretched.
Mechanical Energy Energy associated with motion (KE & PE) Energy associated with motion (KE & PE)
Thermal Energy Energy of particles in an object Energy of particles in an object
Chemical Energy Energy stored in chemical bonds Energy stored in chemical bonds
Electrical Energy Moving electric charges Moving electric charges
Electromagnetic Energy Waves of energy, such as light Waves of energy, such as light
Nuclear Energy The fusion or fission of atoms The fusion or fission of atoms
Kinetic Energy Which of the following is an example of Kinetic Energy? Compacted spring A Boulder atop a mountain B Boulder rolling down a mtn. C Bike at the top of half pipe D
A bow string that is pulled back and ready to fire is… Gravitational PE A Elastic PE B Rubber KE C Elastic KE D
KineticPotential example What is the difference between Kinetic and Potential energy? Give an example of each.
