What is the difference between Weight and Mass?Please give a fair amount of detail!

Weight is how much force is exerted on the body by gravity. It is measured in N. To get Weight you multiply the mass in kg by the gravitational force of the planet that you are on (about 9.81 for earth). Gravity <em>causes</em> weight, which is why if you are an in an impossible scenario where no gravity is acting on you your weight would be 0N.

Mass is how much matter something contains, measured in Grams. A body's mass always stays the same regardless of where it is.

The <em>mass</em> of an object is a measure of how much stuff it's made of. So it's
a property of the object, like the object's length or color. It doesn't depend on
where the object is located right now, or on what else is around it..

The <em>weight</em> of an object is the measure of the gravitational force between it
and something else. The strength of the force depends on the size of both
masses, and also on how far apart they are. So the weight does depend on
where the object is located right now, and on what else is around it.

I think that sums it up fairly well.

An air-track glider undergoes a perfectly inelastic collision with an identical glider that is initially at rest. what fraction

Allisa [31]

In this collision, 1/2 of the initial kinetic energy of the first glider is converted into thermal energy.

<h3>In plain English, what is kinetic energy?</h3>

An object's strength as a result ofstrength an object has as a result or motion is known as kinetic energy. Toorder to accelerate an object, a force must be applied. Applying force requires effort on our part. When the work is done, power is transported to the thing, which causes it to move at the athe new, constant pace.

<h3>What does kinetic energy mean, or what are some instances?</h3>

The motion energy is known as kinetic energy, and it is manifested when a particle, object, or group if particles moves. Any moving object uses kinetic energy, including people walking, baseballs being thrown, food falling from tables, and charged particles in electric fields.

In a sonometer by what change in linear density of wire its velocity becomes double? Keeping tension of wire constant

faltersainse [42]

Answer:

Explanation:

In a sonometer , expression for speed of wave produced can be given as follows .

v = $\sqrt{\frac{T}{m} }$

v is velocity , T is tension in wire , m is density per unit length .

Here v is inversely proportional to square root of m . So if m becomes m / 4

velocity changes as follows .

velocity = $\sqrt{\frac{T}{\frac{m}{4} } }$

= $\sqrt{\frac{4T}{m} }$

= 2v

velocity becomes two times . Hence to make velocity two times , mass per unit length has to be changed to one fourth value , keeping tension constant .

A meter stick whose mass is 290 grams lies on ice. You pull at one end of the meter stick, at right angles to the stick, with a

katen-ka-za [31]

Answer

given,

mass of the stick = 290 grams = 0.29 Kg

Force on the stick on one side = F = 9 N

force acting perpendicular to stick.

magnitude of acceleration

rate of change of angular momentum is equal to Force

rate of change of angular momentum = 9 N

F = m a

$a = \dfrac{F}{m}$

$a = \dfrac{9}{0.29}$

a = 31.034 m/s²

Direction of motion will in the direction of force application or in the direction of change of velocity
