I don't know how to swim fast like you. But I am joining you today. <3
Maria, wanna come for swimming after school today?
No worries. I will teach you
Newton's Third law
No, I am scared. I cannot swim fast.
What is that?
The more force u apply on the water by pushing it,the more the water would push you back which will result in fast swimming. This behavior of equal and opposite reaction force is newton's third law.
I will teach you a scientific method to swim fast today.
Newton's First Law
It was fun swimming. Thank you for the advice, Jerry. But can you tell me how can i start and stop in time while swimming?
Oh, until a force is applied on u, neither can you stop, nor can you move. That's why you have to apply force by your legs on the floor to stop.
Newton's First Law
Did you get hurt? I also got the same feeling of getting pushed back
Ya! Nice to meet you again. Ouch!! The bus just pushed me backwards.
Newton's third law states that every action has an equal and opposite reaction. In swimming when the hands and feet push against the wall, the water pushes back on the swimmer and propels the swimmer forward. In creating an equal and opposite reaction, the swimmer is kept afloat and propelled forward.
Newton's Second Law
Doing my golf ball practise.
Hey, John. What you doing?
Just came from football practice. What about you?
According to Newton's law, when a body is at rest, it will stay at rest until an unbalanced force is applied. This can be noticed by the drag which is felt when the movement starts, is the static force the swimmer is trying to overcome. On the other hand, when a body is in motion, it stays in motion until a force is applied. Like this, once dynamic force is experienced, the swimmer could just continue forever, however, the drag will put to a stop eventually.
Newton's Second Law
Hey Ashley! You are an amazing basketball player. Can you please tell me your techniques?
Law of Inertia: When a bus stops moving, the part of our body, which stays attached with the bus seat, stops moving too, but the front part of our body, being not attached to the bus moves forward. On the other hand, the opposite thing happens when the bus starts moving as explained above. This proves newton's first law that things at rest stays at rest, things in motion stay in motion unless a force is applied on it.
Oh wow, Jerry, we got onto the same bus.
U know why this happens? This happens because of inertia. When the car starts moving from rest position, the part of the your body which is attached to the bus seat also starts moving, but your upper body is not attached to the bus and thus it moves backwards.
Newton's second law states two important things. One of them is that, the acceleration of an object is inversely proportional to the mass of an object. And for this, objects with smaller mass, has more acceleration (rate of change in speed per unit of time)
According to Newton's second law, the acceleration of an object is inversely proportional to the mass of the object. That's why, having a smaller mass, golf ball can go faster than cricket ball.
It's strange how, a golf ball can speed up more than a football. After all, both of them are sport balls.
Newton's Second law states the relationship between the object's mass, acceleration and applied force. The formula being (F=ma). That means the force is mass times the acceleration of the object. The acceleration of an object is proportional to the magnitude of net force. And hence, if the force applied on the ball is increased, the ball will speed up more as well.
Nothing much. It's just a Newton magic. If you hit the ball with double the force you can, the rate at which the ball accelerates (speed up) will be doubled!
