Question

S4: Another example of a contact push/pull interaction is when a soccer player uses his or her muscles to kick a stationary soccer ball. a) Complete the G/R energy diagram below for what happens during this interaction. Below the diagram indicate what the evidence is for the energy changes in the giver and the receiver Contact Push/Pull Interaction Energy Giver Energy Receiver Energy Increase in Decrease in b) Complete this statement of conservation of energy for this interaction assuming no other interactions are occurring at the same time) Decrease in Increase in 0 of

Explanation / Answer

a) the energy giver will push the ground and the energy receiver will be pushed by leg

Decrease in kinetic energy of leg of energy giver  

Increase in kinetic energy of ball

b) decrease in kinetic energy of energy giver = increase in kinetic energy of ball.
