Work is explained as the force that acts on another object  that results in it moving.
2. Power is the amount of work done by an object.  The formula is P=W/T
5. 20 *200N= 4000J
6. 1000J/20s= 200W
7. 900N*100m=90000J
8. 4000J/20s= 20s
9. 210N *1000=210000=500*T; 210000/500=T
T= 420 seconds or 7 minutes.
10. 8000*1000=8000000J
11. 400*2= 800J

2) Power is P=W/T 
Power is measured with watts ]]> 2017-01-25 16:37:51 UTC https://padlet.com/tec430/f7u33bbzlx13/wish/149378154
