Newton's Second Law
Its states a relation between the force applied to a body and rate its speed will change (acceleration). It's a simple equation.
JUST:
F=ma

If you a awake its hard to fall asleep, and if you are sleeping its hard to wakeup.
Newton's First law of motion
or the Law of inertia:
It states that any body's state of motion or rest won't change without exerting a force on it. it raises a concept of inertia like a body's resistance to change.

If a runner runs from A to B through a curved path. Will he be displaced by the same distance he crossed?
Definitely Not !
Displacement is the length between the starting and ending point (straight line) and the distance he crossed was greater due to the curved path.
Do you know the displacement if he goes back to A?

Just keep going! It is as simple as that.

When adding or subtracting unlike fractions. Step one is to make them like by changing the one of the denominators or both by multiplying to find equivalent fractions. Then once the denominators are similar we can subtract the numerators as in like fraction subtraction.

$Similarly to addition, while subtracting like fractions we only subtract the numerators and the denominator stays the sa...$

Similarly to addition, while subtracting like fractions we only subtract the numerators and the denominator stays the same.

Unlike fractions addition starts with making the fractions like, how can that be done? Just multiply both parts of the fraction by a number that will make the the denominator like that of the other fraction. Some times both fractions should be multiplied by different numbers.

Adding fractions is so simple, you just have to know if they are like or not. If yes add the numerators and let the denominator as it is. If not check out the next post.

Equivalent fractions are fractions that are equal but unlike. They come in handy when we need to add and subtract fractions. Fractions that can be reduced to one fraction are all equivalent to each other and the simplest fraction. They are all basically the same.

$What is the difference between like and unlike fractions and does it make addition and subtraction different?$
