Newtons 3 Laws in Swimming

Newtons 3 Laws in Swimming

What Are Newton's Three Laws?

Newtons Second Law

Example 2:

If Chase dives in with an acceleration on 3 m/s/s and he has a mass of 79 kg what is his force?

F=m x a

m= 79 kg F= 79kg x 3 m/s/s

a= 3 m/s/s F= 237 N

F= ?

Newton's Laws of Motion are

*The Law of Inertia

*force=mass x acceleration

*Action=reaction

They explain how force acts upon an object.

First Law of Motion

Newton's first Law of Motion is: an object at rest/in motion will stay at rest/in motion unless acted on by an unbalanced force.

Second Law of Motion

Newton's Second Law of Motion is: force=mass x acceleration

Third Law of Motion

Third Law

Another example of Newtons third law in swimming is the swimmer's hand pushing against the water and the swimmer moving forward because of it.

Newtons third law states that for every acting there is an equal and oppisite reaction to counter it.

First Law of Motion

Examples:

Chase is swimming in the pool at 8 m/s/s. To avoid crushing his head on the concrete wall, he has to slow down and do a flip turn on the wall.

Third Law

Conclusion

An example for the third law in swimming is the force of a person swimming against the equal and opposite force of the water.

Second Law of Motion

Swimming relates back to all three of Newtons laws which are an object in motion stays in motion, force= mass x acceleration, and every action has an equal and opposite reaction. Swimming relates to the first law because a swimmer in motion stays in motion unless acted upon by an unbalanced force. An example of this is a swimmer swimming towards a wall then has to stop on the wall, the wall is the unbalanced force. Swimming relates to Newtons second law because you can use F= ma to calculate a swimmers force if you have their mass and acceleration. An example of this is a swimmer that ways 80kg going 5m/s/s you could use those numbers to calculate their force. Lastly swimming can relate to Newtons third law by the swimmer swimming being a action and the water's force being the reaction. An example of this would be a swimmer's hand pushing against the water and the swimmer moving forward because of it. In conclusion, swimming relates to an object in motion stays in motion, force= mass x acceleration, and every action has an equal and opposite reaction.h

Example 1:

Chase is swimming with 10 m/s/s of acceleration. He weighs 79 kilograms. Chase will have 790 Newtons of force.

mass=79 kilograms f=ma

acceleration=10 m/s/s f= 79 kilograms x 10 m/s/s

force=? f=790 Newtons
