Newton's Third Law

This week in science, we learnt that if there is an arrow on a force diagram that is facing down, the object is accelerating or decelerating. It is not showing an object going in a direction.

Newton's third law claims that the amount of force exerted by an object gets exerted back on the object that exerted that the force. This is cenerio a i am using as an example: (to the left)

The young girl pushes the old lady and soon they both will go in opposite directions the same distance from the origon that the girl had first applied the pushing force.

Newton second Law explains that force is equal to mass multiplied by acceleration. F=(m/a)

And that concluded our week in science.

Force part two

this week in science, we learned more on the unit force. We discovered that there is gravity,"Force of the Earth puling on us": is weight.
We also discussed the idea of the mass or massiveness. Mass is the amount of matter that is consisted in a substance.

Mass is what gives us weight. It is because the mass of a substance is pulling down on us, that of force that is pulling down on us gives us our weight!

In space, there is no gravity until we come close to a huge mass like the moon or another planet. So, if we launch a rocket into space, the rocket will stay in the course that we put it in. Then the rocket will start accelerating toward a mass because of the mass' gravity is bulling down on the rocket toward the mass. So eventually, with the gaining acceleration of our rocket, the rocket will crash into the mass.

Since the moon has a lesser gravity than the Earth, the moon will have a less pull on the objects near it. Or less gravity in the objects near it.

Force

This week in science, we learnt that there is something that makes things and us move. and that is force. Force is a push or a pull on a object.

So, we learnt how to make force diagrams. a force diagram is a diagram that shows all the different forces exhibited on the object of interest.

If the object of interest is staying in the air, either held up or stagnant in the air, that means there is a positive force and is contradicted by a negative force and so, that means there is 0 newtons being exited on the object of interest which means the object is staying in the air or is being held up.

This is how i know how many newtons are being applied to the object to make it stay in the air:(to the left)
