Image result for what is the force the when does when Gravity pushes you​

The important thing to remember is that gravity is neither a push nor a pull; what we interpret as a “force” or the acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward.

Image result for what is the force the when does when Gravity pushes you​

The important thing to remember is that gravity is neither a push nor a pull; what we interpret as a “force” or the acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward.

Answer:

It is called gravitational force.

Explanation:

[tex]{ \boxed{ \rm{F = \frac{GM_{a} m _{a}}{ {r}^{2} } }}}[/tex]

→ Assume you are in space and you have a mass of ma, and you are r metres from the Earth of mass Ma. The force F will be experienced and you will tend to be pulled towards the Earth when you are in its gravitational field.

c  

Explanation:  

it was a crash they both lost momentum

Answer:

Explanation:

100 kph = 27.8 m/s

80 kph = 22.2 m/s

v² = u² + 2as

a = (v² - u²) / 2s

a = (22.2² - 27.8²) / (2(88))

a = -1.578282828...

a = -1.58 m/s²

t negative sign means the acceleration opposes the initial velocity.

t = Δv/a

t = (22.2 - 27.8) / -1.57828

t = 3.52 s

Answer:what is the problems

Explana:

Electricity is the movement of electrons around a closed-loop known as a circuit.

Magnetism is a phenomenon that results from the motion of electric charges phenomenon resulting in the attractive and repulsive forces between objects.

Both electricity and magnetism are known to be similar in nature in that a magnetic field that is changing can create an electric field and also a changing electric field can create a magnetic field.

Juan’s velocity between 0-5 seconds would be 2 m/s, the slope of the position time graph represents the velocity of the object and between the 0-5 seconds slope of the line is 2.

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

velocity= total displacement/Total time

As given in the problem we have to find the velocity of Juan between 0-5 seconds.

The displacement covered between 0-5 seconds is 10 meters.

the time taken to change position is 5 seconds,

the velocity of the Juan = 10/5

                                 =  2 meters/seconds

Thus, its velocity of Juan comes out to be 2 meters/second.

The statements which are false from the choices above are:

In scenarios of like charges, the potential energy is always positive, that is because we need to put energy in the system to bring like charges closer together.

Conversely, for unlike charges, the potential energy of the pair of unlike charges is negative, as a result of the energy expended by the system in pushing the charges away from each other.

Answer:

First scenario,

From 2nd Newton's law

F = ma

from the above eqn, it's evident

a = F/m

that is to say, acceleration is inversely proportional to mass

The greater the mass, the smaller the acceleration and the higher the acceleration, the smaller the mass.

Thus, You was in the wagon when it had the greatest acceleration because You has the smaller mass and thus the acceleration will be greater.

Second scenario,

Since Sara pulls with greater force and Force is directly proportional to acceleration according to the second Newton's law,

F = ma

then, when You is in the wagon it had greater acceleration since they have the same mass.

Hi there!

We can use the conservation of energy:

Ei = Ef

The initial energy involves kinetic energy while the final energy involves maximum elastic potential energy, so:

1/2mv² = 1/2kx²

We can cancel out the 1/2s for ease of solving:

mv² = kx²

Plug in given values to solve for x:

√(mv²/k) = x

√(5.7)(12²)/(150)) = x

x = 2.339 m

Answer: 1 hour

Explanation: Focus on the units; 70 miles per hour means that each hour, you will travel 70 miles

or you can use the equation time = distance/speed. You have 70miles/ 70mph = 1hour

Following are the solution to the given points:

Given:

[tex]\to mass(m)= 65\ kg\\\\\to h=10.0 \ m\\\\\to g=9.8 \ \frac{m}{s^2}[/tex]

To find:

gravitational potential energy(GPE)=?

kinetic energy(KE)=?

concept=?

v=?

Solution:

For point a:

[tex]\to GPE= mgh[/tex]

             [tex]= 65 \times 10 \times 9.8\\\\ = 6370 \ J\\\\[/tex]

For point b:  

[tex]\to KE=\frac{1}{2} m v^2\\\\[/tex]

           [tex]=\frac{1}{2} \times 65 \times 14^2 \\\\=\frac{1}{2} \times 65 \times 14 \times 14 \\\\= 65 \times 14 \times 7 \\\\=6370\ J\\[/tex]

For point c:

As we've seen, there really is no force acting, and the mechanic KE: GPE is used. Because legitimate is conserved. Home energy loss means GPE must be equal to KE gain.

For point d:

A diver has risen 5 feet above the surface. As a result, according to the energy conservation law:

[tex]\to U_i + K_i= U_f + K_f\\\\ \to mg \times h + 0 = mg \times \frac{h}{2} + \frac{1}{2} m v^2\\\\ \to 9.8 \times 10 = 9.8 \times 5 + \frac{v^2}{2}\\\\\to 9.8 \times 10 - 9.8 \times 5 = \frac{v^2}{2}\\\\\to \frac{v^2}{2} =9.8( 10 - 5) \\\\\to v^2 =9.8( 10 - 5) \times 2 \\\\\to v^2 =9.8\times 5 \times 2 \\\\\to v^2 =98 \\\\\to v =98\ \frac{m}{s^2} \\\\[/tex]
