Hi,
Can someone please give an example relating to each of the 3 of Newton's Laws in a footy kick?
EXAMPLE
1st Law can be seen as ball continues travelling in a horizontal range until it is acted upon by external force, gravity
Hi Amy,
You've got the first law right, that's a decent example.
It may be easier for you to simplify the laws before finding examples. So, Newton's first law is the law of inertia. The second law is the law of force. The third is that, for every action, there is an equal and opposite reaction, almost like a trade in energy.
In football, we can see inertia in the way a ball flies, it's trajectory, when kicked. The trajectory will curve and/or be interrupted by external forces such as gravity or another player.
Force, which is calculated by mass x acceleration, can be shown when the ball is hit. Coming into contact with the athlete's foot, which has large mass and force, will generate acceleration in the ball which will create a successful kick.
Newton's Third Law is displayed by the act of kicking the football, (the physical meeting of the player's foot and the ball) where equal force from the other will be placed on both the ball and the player's foot. However, the football's mass is much less than that of the player, making the acceleration of the ball much greater and thus much more noticeable in comparison to the athlete.
This is not to say there is no reaction, but it is much less visible.
Hope this helps
