Question

1. match each of newtons laws to the correct answer choice. * maya hits a curb while riding her bike. the bike stops moving, but maya is thrown into the air. a bird flaps its wings, using them to push air downward. air pushes upward on the bird allowing the bird to fly. peter pushes on two boxes with equal force. the first box is filled with balloons. the second box accelerates at a greater rate than the first box. newtons 1st law of motion: the law of inertia newtons 2nd law: f=ma newtons 3rd law: law of action - reaction

Explanation:

1. Maya hits a curb while riding her bike. The bike stops, but Maya is moving, but Maya is thrown into the air. - This is an example of inertia (Newton's 1st Law). An object in motion tends to stay in motion. Maya was in motion with the bike and when the bike suddenly stopped due to the curb, her body wanted to continue moving forward.
2. A bird flaps its wings, using them to push air downward. Air pushes upward on the bird allowing the bird to fly. - This is an example of Newton's 3rd Law (Law of Action - Reaction). The action is the bird pushing air down, and the reaction is the air pushing the bird up.
3. Peter pushes on two boxes with equal force. The first box is filled with balloons. The second box accelerates at a greater rate than the first box. - According to Newton's 2nd Law ($F = ma$), when the force ($F$) is the same, a smaller - mass object will have a greater acceleration. The box with balloons likely has less mass, so it accelerates more.

Answer:

1. Newton's 1st Law of Motion: Inertia - Maya hits a curb while riding her bike. The bike stops, but Maya is thrown into the air.
2. Newton's 3rd Law: Law of Action - Reaction - A bird flaps its wings, using them to push air downward. Air pushes upward on the bird allowing the bird to fly.
3. Newton's 2nd Law: $F = ma$ - Peter pushes on two boxes with equal force. The first box is filled with balloons. The second box accelerates at a greater rate than the first box.
