4)Explain why,when a soccer ball is kicked, the action and reaction forces don't cancel each other.
a)The force of the player's foot on the ball greater than the force on the ball on the player's foot.
b)They act on two different objects.
c)The reaction force happens after the action force.
It looks like A.
A) the force of the player's foot on the ball greater than the force of the Ball on the players foot.
The correct answer is b) They act on two different objects.
When a soccer ball is kicked, the action force is the force exerted by the player's foot on the ball, pushing it forward. The reaction force is the equal and opposite force exerted by the ball on the player's foot, pushing it backward.
These forces do not cancel each other out because they act on two different objects. The action force acts on the ball, while the reaction force acts on the player's foot. As per Newton's third law of motion, these forces are equal in magnitude and opposite in direction, but they do not cancel each other because they act on separate objects.
Therefore, the action force and the reaction force coexist and do not cancel each other out in the context of a soccer ball being kicked.
When a soccer ball is kicked, the action and reaction forces don't cancel each other out because they act on two different objects. This principle is known as Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
Let's break down the scenario:
a) The force of the player's foot on the ball is greater than the force on the ball on the player's foot.
When a player kicks a soccer ball, they exert a force onto the ball. This force causes the ball to accelerate and move in the opposite direction. However, according to Newton's Third Law, the ball also exerts an equal and opposite force on the player's foot. The force on the player's foot is indeed present, but it is relatively small compared to the force the player exerted on the ball.
b) They act on two different objects.
The action force occurs between the player's foot and the soccer ball. The player's foot exerts a force on the ball, propelling it forward. Simultaneously, the reaction force occurs between the soccer ball and the player's foot. The ball exerts an equal and opposite force back on the player's foot. Since these forces act on different objects (the ball and the foot), they cannot cancel each other out.
c) The reaction force happens after the action force.
The time sequence of the action and reaction forces is important to note. The action force is applied by the player's foot on the ball, causing the ball to move. Almost instantly after, the reaction force is exerted by the ball on the player's foot. The reaction force doesn't negate the action force; instead, it is the ball's response to the force exerted by the foot. Both forces happen simultaneously, but they are distinct and act in opposite directions.
In summary, the action and reaction forces don't cancel each other out when a soccer ball is kicked because they act on different objects and happen simultaneously, following Newton's Third Law of Motion.
