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.
