Place the letter "K" next to any example of kinetic energy. Place the letter "P" next to any example of potential energy 1. a biker biking down a street K (mechanical energy) 2. a bow and arrow stretched and ready to fire P (elastic energy) 3. you hold a shot put in your arm above the ground and are about to throw P (gravitational energy) 4. a match is used to light a fire K (heat energy) 5. a race car has just filled his tank to full and is waiting for green light P ( chemical energy)
Answer the following questions: 6. A full luggage is pulled with a force of 200N. The luggage is pulled a distance of 30m How much work is being done? W=Fxd W=200Nx30m W=6000J
6000 J of work is being done to pull the luggage a distance of 30m with a force of 200N
7. Timmy has 3 models of inukshuks. It takes him 800N to move each inukshuk 2m. How many Joules of work will it take to move the 3 inukshuks 2m?
W=Fxd =800Nx2m =1600J
Total amount of work =1600Jx3 =4800J
It will take Timmy 4800J of work to move the three inukshuks a distance of 2m.
