Explain using the laws of physics why the moon orbits the earth.

Physics
1 answer:
weqwewe [10]3 years ago
7 0

Answer:

the moon orbit's the earth in part because of centrifugal force added to the gravity of the earth and sun keeps the moon in the perfect balance that it is in.

Explanation:

centrifugal force is when an object pulls "out" like when you swing some around your body it pulls outward which is why the string is taught so the force pulling it in is the same as the force pulling out as the moon orbits.

Kenetic energy increasing because velocity increased
Ymorist [56]

Answer:

Explanation:

The formula for kinetic energy  Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.

If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.

In which situation is maximum work considered to be done by a force
Katena32 [7]

Answer:

  • Work done is maximum when the movement of object is in line and direction of force.  

OR

  • Work done is maximum, when displacement takes place along the direction of force.
  • Work done is given by the equation

                                W = F.S

                            <em>     W  = F. S cos Θ</em>

<em>When cos Θ = 0° ; cos 0 = 1</em>

(1 point) Suppose a spring with spring constant 1 N/m is horizontal and has one end attached to a wall and the other end attache
fredd [130]

Answer:

Explanation:

Given that,

The spring constant

K = 1N/m

Frequency of motion

f = 14Hz

We want calculate the mass m?

The frequency of spring system is related to the mass by

From w = √k/m

Where w = 2πf

f = 1/2π √k/m

Where,

w is angular frequency in rad/s

m is mass of object attached in kg

k is the spring constant in N/m

f Is the frequency in Hz

Then, make m subject of formula

Multiply both sides by 2π

2πf = √k/m

Square both sides

4π²f² = k/m

Then, k= 4π²f² × m

m = k / 4π²f²

m = 1 / (4π² × 1.4)

m = 1 / 55.27

m = 0.0181 kg

m= 18.1 g

The mass of the object attached in 18.1 g or 0.0181 kg

Who discovered laws of gravity and motion? He discovered aspects of light and color, leading to today's spectrum analysis
Vitek1552 [10]

Answer:

Sir Isaac Newton

Explanation:

The laws according to which bodies move and how one body attracts another body were developed by Newton. The three laws of motion and the law of universal gravitation were developed by Newton.

In the seventeenth century almost all the refracting telescopes exhibited color distortion. Newton believed that white light had a spectrum which was the reason for this distortion. The lens of a refracting telescope used to act like a prism which caused the dispersion of light proving Newton's hypothesis.
