What was Galileo’s contribution to the study of motion?

babunello [35]

Before giving you the answer straight away, I’d like to make sure you understand each option.

FIRST OPTION

“He developed the three laws of motion."

This option is not only the incorrect answer, but it is an incorrect statement. Galileo did not develop the three laws of motion. Isaac Newton was the one to compiled the three laws of motion.

SECOND OPTION

“He was the first to systematically study force and motion."

This option is a statement is true, and it could also be the correct answer. Galileo Galilei used experiments to search for the cause of motion.

THIRD OPTION

“He was the first to discover gravity."

This option is not only the incorrect answer, but it is an incorrect statement. Galileo was not the person to discover gravity. Sir Isaac Newton was the first to discover gravity.

FINAL OPTION

“He improved on Newton's laws."

This option is not only the incorrect answer, but it is an incorrect statement. Galilei did not improve Sir Isaac Newton’s laws.

Now that we’ve gone through each of the options individually, we can go ahead and determine the correct answer to the question, which is...

B ) He was the first to systematically study force and motion.

A student was traveling to see his grandmother who lives 15 miles north oh his home he started from rest and maintained a pace o

N76 [4]

Explanation:

Given parameters:

Distance = 15miles north = 24140.2m

Initial velocity = 0m/s

Final velocity = 4m/s

Unknown:

Speed, velocity and acceleration = ?

Solution:

The speed is the distance divide by time. It is a scalar quantity and has no directional attribute.

Speed = $\frac{distance }{time}$

The speed of the student is 4m/s

Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude;

Velocity = $\frac{displacement}{time}$

The velocity of the student is 4m/s due north

Acceleration is the change in velocity with time;

To find the acceleration, we use

v² = u² + 2as

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance

4² = 0² + 2x a x 24140.2

a = $\frac{16}{2 x 24140.2}$ = 0.00033m/s²

A 65 kg student sits 3 m away from a 70 kg student. What is the magnitude of the gravitational force between the two students?

LiRa [457]

Answer:

$F=3.37\times 10^{-8}\ N$

Explanation:

Given that,

Mass of student 1, m₁ = 65 kg

Mass of student 2, m₂ = 70 kg

The distance between the students, d = 3 m

We need to find the magnitude of the gravitational force between the two students. The formula for the magnitude of the gravitational force between two masses is given by :

$F=G\dfrac{m_1m_2}{d^2}\\\\F=6.67\times 10^{-11}\times \dfrac{65\times 70}{(3)^2}\\F=3.37\times 10^{-8}\ N$

So, the gravitational force between the two students is $3.37\times 10^{-8}\ N$ .
