Answer:

The gravitational force between these two objects is around $F_{g}=6.674*10^{-11} N$

Explanation:

The gravitational force can be written as:

$F_{g}=G\frac{m_{1}m_{2}}{r^{2}}$

Here:

G is the gravitational constant $G = 6.674*10^{-11} m^{3}kg^{-1}s^{-2}$
m(1) is the first mass
m(2) is the second mass
r is the distance between two bodies.

If we see, the gravitational constant is a very small number, therefore the gravitational force is representative just when we have to massive bodies. Let's suppose that the mass of the pencil is 0.1 kg and the eraser is 0.1 kg too, the distance between them would be around 10 cm or 0.1 m, for instance.

Now let's calculate the gravitational force of these two bodies.

$F_{g}=G\frac{0.01*0.01}{0.1^{2}}$

$F_{g}=6.674*10^{-11} N$

As we see it is very small force, so it is negligible relation to the earth gravitational force. That is why these two objects do not move towards each other.

I hope it helps you!

What is the meaning of Constant Acceleration?

lora16 [44]

Any change in speed or direction of motion is acceleration.

Constant acceleration can mean ...

-- speeding up at a constant rate . . . gaining the same amount
of speed each second.

-- slowing down at a constant rate . . . losing the same amount
of speed each second.

-- changing direction at a constant rate . . . for example, going
around a circular path at a constant speed.

A wheel of radius 0.23 m, which is moving initially at 25.0 m/s, rolls to a stop in 246.0 m. The wheel's rotational inertia is 0

Digiron [165]

Answer: -1.27 m/s^2

Explanation:

a = - V^2 / 2x

a = -(25^2) / 2 x (246) = 1.27 m/ s^2

Therefore the linear acceleration of the wheel is - 1.27 m/s^2
