Answer:
Netwon's first law: The little girl will not move until she uses her leg to apply a force forward.
Newton's second law: The greater the push of the skater's foot against the ice, the faster he will accelerate.
Newton's third law: The skates are pushing on the ice and the ice is pushing back on the skates
Step-by-step explanation:
Newton's first law is that a body at rest will remain at rest until a force is acted upon it. So, the correct example would be the little girl because she needs to push off her leg to start going forward. She is at rest until she does so.
Newton's second law is that the force acting upon an object is equal to the mass of the object times the acceleration. The more force the more acceleration, so the correct example would be the skater pushing against the ice in order to accelerate faster. The more force he exerts the faster acceleration.
Newton's third law is for every action there will be an equal and opposite reaction. The correct example would be the skater pushing down on the ice and the ice exerting the same force to the skate. Both are exerting the same force on each other, like the law says.
Hope this helps!!
