How does inertia affect the motion of an object?

Physics
1 answer:
Furkat [3]4 years ago
4 0

<u>Inertia affects the motion of an object as follows:</u>

When an object is in motion, it will continue to be in the same state unless otherwise some outside force is being applied to it. Thus, inertia affects the motion of an object. It restricts some other force being acted upon the object.

But mass of an object is directly proportional to inertia. So when the inertia is more on an object, it means that the object has more mass. For example, if there are two similar bricks, one that is made up of mortar and the other one is made of Styrofoam.

To identify which brick is made of Styrofoam without lifting the bricks, push both the bricks with equal force, the one that has less resistance tends to move faster. This means that it has less inertia and hence less mass.

A cold block of metal feels colder than a block of wood at the same temperature. Why? A hot block of metal feels hotter than a b
tino4ka555 [31]

: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects

During the time that the blocks are in contact, describe whether the center of mass of the two-block system is speeding up, slow
iVinArrow [24]

Answer:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Explanation:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Equation:

P=mv

This equation holds if no external force is acting on the system it means the momentum of the system is constant.

In our case, there is no external force which means the total momentum of system is constant:

P=constant

Total mass of system is also constant:

m=constant

It means the velocity of the system is constant (from above equation) thus center of mass of the two-block system is staying the same

A circular loop of flexible iron wire has an initial circumference of 165.0cm, but its circumference is decreasing at a constant
djverab [1.8K]

Answer:

0.005 V

Explanation:

We are given that

Initial circumference of circular loop=C=165 cm

Rate of circumference,\frac{dC}{dt}=12 cm/s

Magnetic field,B=0.5 T

We have to find the induced emf at time t=9 s

We know that induced amf,E=\frac{Bd(A)}{dt}

Area of circular coil,A=\pi r^2

E=B\frac{d(\pi r^2)}{dt}=B(2\pi r)\frac{dr}{dt}

Circumference of circular coil,C=2\pi r

165=2\pi r

r=\frac{165}{2\pi}

\frac{dr}{dt}=\frac{1}{2\pi}\frac{dC}{dt}=\frac{1}{2\pi}\times (12)=\frac{6}{\pi} cm/s=\frac{6\times 10^{-2}}{\pi} m/s

Radius of coil at time t=9 s

r=\frac{165}{2\pi}-(\frac{6}{\pi}\times 9)=9.08 cm=9.08\times 10^{-2} m

1 m=100 cm

E=-0.5(2\pi\times 9.08\times 10^{-2})\times \frac{6\times 10^{-2}}{\pi}=-0.005 V

Magnitude of induced emf=0.005 V
