Kinetic Energy

• energy due to motion

•  $\frac{1}{2}mv^2$  

Work energy theorem

• How might kinetic energy and work be connected? Discuss

Work energy theorem

• Total work done on an object equals the change in kinetic energy

•  $W_{total_{ }}=\ \Delta KE$  

Potential energy

• Gravitational = mgh

• Spring=

   $\frac{1}{2}kx^2$  

• k=spring constant

• x=distance of stretch or compression
