What is the term for the principal that an object in motion remains in motion until it is met by an outside force?

Papessa [141]

The term for the principal that an object in motion remains in motion until it is met by an outside force is called inertia

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force .This principal is named as inertia .

Every matter have inertia , a property to remain in that very position until unless it is been forced on them to change their position .

Inertia is a property of matter that causes it to resist changes in velocity (speed and/or direction). According to Newton's first law of motion, an object with a given velocity maintains that velocity unless acted on by an external force. Inertia is the property of matter that makes this law hold true.

A net force of Fnet acts on an object, causing the object to accelerate at a rat of 9m/s/s. what is the acceleration rate in a s

Readme [11.4K]

The new acceleration is c) 18m/s/s

Explanation:

Net force, mass and acceleration of an object are related by Newton's second law of motion:

$F=ma$

where

F is the net force on the object

m is its mass

a is its acceleration

In the first trial of this problem, a net force of $F_{net}$ is applied to the object, causing an acceleration of

$a=9 m/s^2$

Calling the mass of the object 'm', this means that

$F_{net} = ma = 9m$ [N] (1)

In the second trial, the force applied is $2F_{net}$ , so we have

$2F_{net} = ma'$

where a' is the new acceleration. Substituting (1) into the second equation, we find:

$2(9m) = ma' \rightarrow a' = 18 m/s^2$

This is because the acceleration is directly proportional to the force applied: therefore, if the force applied doubled, the acceleration doubles as well.

Lightning occurs when there is a flow of electric charge (principally electrons) between the ground and a thundercloud. The maxi

Korolek [52]

Answer:

2C charge will flow from ground and cloud

Explanation:

We have given rate rate of flow of charge $\frac{dq}{dt}=20000C/sec$

Time is given as $t=100\mu sec=100\times 10^{-6}=10^{-4}sec$

WE have to find the how much charge flows between the ground and cloud in this time

So the charge flow is given by $\frac{dq}{dt}\times t=20000C/sec\times 10^{-4}=2C$

So 2C charge will flow from ground and cloud

If the gradient of an Extension versus Force graph was found to be 5.6, then what is the value of the spring constant? *

worty [1.4K]

Answer:

5.6

Explanation:

F=kx is the formula for spring force. If Extension versus Force was graphed, a linear relation would appear, where the slope is the k value, aka the spring constant.
