**Newton's First Law of Motion **:

An object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

Here this statement is best represented by the statement : *Unbalanced forces cause an object to move.** ***[**** ****option**** ****c**** ****]**

**More**** to**** know**** ****:****-**

Newton's 3 laws of motion :-

**Newton's**** ****First**** Law**** of**** Motion**** ****:****-**

It states that an object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .

**Ex**** ****-**** ** (i) We tend to fall backwards while standing in the bus , when it starts suddenly.

(ii) We tend to fall forward while standing in the bus , when it stops suddenly.

**Newton's ****Seco****nd**** Law of Motion :-**

It states that the rate of change of momentum is directly proportional to the applied force in the direction of the force . That is ∆p [tex]\propto[/tex] Force .

**Ex**** ****-**** **(i) When we push car & a truck with same force the car will have Greater acceleration due to less mass . (Imaginary case ).

(ii) We feel easy to push a empty cart than a full cart .

**Newton's ****Third**** Law of Motion :-**

It states that every action has equal and opposite reaction .

**Ex**** ****-**** **(i) We are able to walk on ground due to Newton's third law of motion .

(ii) When we push wall it also applies equal and opposite force .

"**Unbalanced **forces cause an **object **to move " is the sentence that describes **Newton's first law.**

A **body **remains in the state of **rest **or uniform **motion **in a **straight **line unless and until an **external **force acts on it.

The **object **is to be rest if the **velocity **and **acceleration **are zero. When an object is in **motion**, **velocity **is **not **equal to **zero **(v ≠ 0) but **acceleration **(a = 0) is equal to **zero**. Therefore, the **object **will continue in motion with **constant **velocity in the **same **direction.

Example:

If we **jump **from a bus while **moving**, our body will be like still moving in the same **direction **of the vehicle. When your feet hit the ground, the **grounds **act on your feet and stop moving. You will fall because the upper part of your body didn't stop and you will **fall **in the **direction **you were moving.

If the **object **have the greater **mass**, then the object will have more **inertia**. Forces can change the **object's **motion.

Hence, **Option D **is the correct answer.

i really need help please just answer at least one

**Answer:**

9) a = 25 [m/s^2], t = 4 [s]

10) a = 0.0875 [m/s^2], t = 34.3 [s]

11) t = 32 [s]

**Explanation:**

To solve this problem we must use kinematics equations. In this way we have:

9)

a)

[tex]v_{f}^{2} = v_{i}^{2}-(2*a*x)\\[/tex]

where:

Vf = final velocity = 0

Vi = initial velocity = 100 [m/s]

a = acceleration [m/s^2]

x = distance = 200 [m]

**Note: the final speed is zero, as the car stops completely when it stops. The negative sign of the equation means that the car loses speed or slows down as it stops.**

0 = (100)^2 - (2*a*200)

a = 25 [m/s^2]

b)

Now using the following equation:

[tex]v_{f} =v_{i} - (a*t)[/tex]

0 = 100 - (25*t)

t = 4 [s]

10)

a)

To solve this problem we must use kinematics equations. In this way we have:

[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]

**Note: The positive sign of the equation means that the car increases his speed.**

5^2 = 2^2 + 2*a*(125 - 5)

25 - 4 = 2*a* (120)

a = 0.0875 [m/s^2]

b)

Now using the following equation:

[tex]v_{f}= v_{i}+a*t\\[/tex]

5 = 2 + 0.0875*t

3 = 0.0875*t

t = 34.3 [s]

11)

To solve this problem we must use kinematics equations. In this way we have:

[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]

10^2 = 2^2 + 2*a*(200 - 10)

100 - 4 = 2*a* (190)

a = 0.25 [m/s^2]

Now using the following equation:

[tex]v_{f}= v_{i}+a*t\\[/tex]

10 = 2 + 0.25*t

8 = 0.25*t

t = 32 [s]

An object with a charge of 1.2 C is located 4.5 m away from a second object that has a charge of 0.36 C. Find the electrical force that the objects exert on each other. Use 8.988×10 N⋅m2/C2 for the value of Coulomb's constant. Give your answer to two decimal places.

**Answer:**

[tex]1.917*10^8\ N[/tex]

**Explanation:**

Coulomb's law states that the electric force between two charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them. It is given by the formula:

[tex]F=k\frac{q_1q_2}{r^2}\\ \\q_1=first\ charge = 1.2C,q_2=second\ charge=0.36C,k=coulomb\ constant=8.988*10^9 N.m^2/C^2, r=distance=4.5m,F=force\\\\F=8.988*10^9*\frac{1.2*0.36}{4.5^2} =1.917*10^8\ N[/tex]

how is kinetic energy is stored

Answer:

Explanation:

Kinetic energy can be stored. For example, it takes work to lift a weight and place it on a shelf or to compress a spring. ... Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.

Two fish swimming in a river have the following equations of motion:

X 1 = - 6.4 m + (- 1.2 m/s) t

X 2 = 1.3 m + (- 2.7 m/s) t

Which fish is moving faster?

**Answer:**

The second fish, X2, is moving faster than the first fish, X1

**Explanation:**

The given parameters for the equation of motion of the fishes are;

X1 = -6.4 m + (-1.2 m/s)×t

X2 = 1.3 m + (-2.7 m/s)×t

The given equation are straight line equations in the slope and intercept form, where the slope is the speed and in m/s and the intercept is the starting point of swimming of the fishes

For the first fish, the intercept = -6.4 m, the slope = the speed = -1.2 m/s

For the second fish, the intercept = 1.3 m, the slope = the speed = -2.7 m/s

Whereby the fishes are swimming in the opposite direction of the measurement of length, we have;

The magnitude of the speed of the second fish [tex]\left | -2.7 \ m/s \right | = 2.7 \ m/s[/tex], is larger than the magnitude of the speed of the first fish [tex]\left | -1.2 \ m/s \right | = 1.2 \ m/s[/tex]

Therefore, the second fish, X2, is moving faster than the first fish, X1.

Please help!! The graph in the figure shows the position of a particle as it travels along the x-axis. What is the magnitude of the average speed of the particle between t = 1.0 s and t = 4.0 s?

The **uniform movement **allows to find the **average speed**, for which the correct answer is:

B) 1.3 m / s

**Kinematics **studies the movement of bodies, establishing relationships between **position, velocity** and **acceleration**. In the special case that the **acceleratio**n is **zero** the motion is called **uniform motion**.

v = [tex]\frac{\Delta x}{\Delta t}[/tex]

Where v is the velocity, Δx is the position variation and Δt is the time variation in the analyzed interval.

In this case

v = [tex]\frac{2.0 - (-2.0)}{4.0\ -1.0}[/tex]

v = 1.33 m / s

In conclusion using the **uniform motion** ratios we can find that the correct answer for the **average velocity** is

B) 1.3 m / s
