For each of following situations ,identify what creates on one of the forces that creates the motion described (there may be many) A. a flag flag back and forth at the top of a flagpole. B.a soccer ball is passed from one player to another C. a large piece of hail falls toward the ground .
If you really want an expert to help you, be sure to follow directions and type your subject in the School Subject box. Any other words, including obscure abbreviations, are likely to delay responses from a teacher who knows that subject well.
A. wind
B. force applied by a kicker's foot; aerodynamic force
C. gravity (weight), air resistance
A. The force that creates the motion of a flag flapping back and forth at the top of a flagpole is the wind. The wind pushes against the flag, causing it to move in a swinging or waving motion.
B. The force that creates the motion of a soccer ball being passed from one player to another is the force applied by the player's foot. When a player kicks the ball, they impart a force that propels the ball forward towards another player.
C. The force that creates the motion of a large piece of hail falling toward the ground is gravity. Gravity is an attractive force between objects that pulls them towards each other. In this case, the force of gravity pulls the hailstone down towards the Earth's surface, causing it to fall.
A. For the motion of a flag flapping back and forth at the top of a flagpole, one of the forces that creates this motion is the wind. When there is wind blowing, it exerts a force on the flag, causing it to move back and forth.
To determine the force in this situation, you can observe the movement of the flag and infer that there is an external force acting on it. By understanding that wind is commonly responsible for such movements, you can conclude that the force causing the flag to flap is the force exerted by the wind.
B. In the case of a soccer ball being passed from one player to another, there are a couple of forces involved. One of the forces that creates the motion of the ball is the kick or strike made by the player initially passing the ball. When the player kicks the ball, they exert a force on the ball, propelling it in a specific direction towards the other player.
Another force involved is the force of gravity acting on the ball. As the ball travels through the air, it is under the influence of gravity, causing it to follow a curved trajectory towards the ground. However, in this specific situation, the motion described is the passing of the ball, so the initial kick force is the primary force causing the ball to move.
To determine the forces involved in this case, you can analyze the motion of the ball and consider the actions of the players. By observing that the ball is moving between two players and reasoning that it must have been kicked or struck by the first player, you can identify the initial kick force as the force creating the motion.
C. When a large piece of hail falls toward the ground, the primary force creating this motion is gravity. Gravity is a fundamental force that attracts objects with mass towards each other, causing them to accelerate downward. In the case of the hail, as it falls, gravity continuously pulls it towards the Earth's surface.
To determine the force in this situation, you can analyze the motion of the hail and consider the known influence of gravity on objects. By observing the falling motion of the hail, you can conclude that the force causing the motion is the gravitational force pulling the hail downwards.
