Chapter 4 Work and Energy
Work is the use of force to move an object
Force is necessary to do work
Work - the use of force to move an object some distance
Force, Motion, and Work
Calculating work
Joule - measurement also known as the Newton-meter
Objects that are moving can do work
Power is the rate at which work is done
Power can be Calculated from work and time
Power - the rate at which you do work
Calculating power from work
Watt - the unit of measurement for power
Horse Power
Horse Power - the amount of work a horse can do in a minute
Power can be calculated from energy and time
Calculating power from energy
Everyday power
Energy is Transferred when work is done
Work transferred energy
Work Changes potential and kinetic energy
Kinetic Energy - The energy of motion
Potential Energy - stored energy
Calculating Gravitational potential energy
Calculating kinetic energy
calculating Mechanical Energy
Mechanical energy - energy possessed by an object due to its motion or position
The total amount of energy is constant
Law of conservation of energy -
Conserving mechanical energy
Losing mechanical energy
forms of energy
Thermal energy - the energy of the speed of the molecules the faster the molecules the more thermal energy
Chemical Energy - energy stored in chemical bonds
Nuclear energy - potential energy stored in the nucleus of an atom
Electromagnetic energy - energy associated with electrical and magnetic interactions
