What is the difference between mass and momentum?
VLD [36.1K]

Answer & Explanation:

Definition:

Mass informs us about how much matter is present in a body. It is the measure of the inertia of a body. It can be measured by measuring the force of gravity acting on it on earth.

On the other hand, Momentum is the quantity of motion of the body. It depends depends upon velocity and the direction of the motion of the body.

Unit:

The SI unit of mass is kilogram (kg) while the SI unit of momentum is kg.m.s-1.

Formula:

Mass = Momentum / Velocity

Momentum = Mass * Velocity

or p = mv

Type:

Mass is scalar quantity while Momentum is a vector quantity.

HELP!!
QveST [7]

Answer:

Total displacement 155 m

Explanation:

From the question, the formula to apply will be that of cosine rule where:

c=\sqrt{a^2+b^2-2ab*cosC}

where

a= 43 m , b=130m and c =? , <C=28° + 90° =118°

Substituting values in the equation as;

c=\sqrt{43^2+130^2-2*43*130*cos118}

c=\sqrt{1849+16900-11180*-0.46947} \\\\c=\sqrt{1849+16900+5249} \\\\c=\sqrt{23998} \\\\\\c=155m

A 2.0kg pendulum swings from point A of a height of 0.10m to a point B of the same height. The heights are relative to the lower
mr_godi [17]
Please press “Thanks!” after viewing my answer:
The change in Gravitational Potential Energy (GPE) is actually 0! Think about it:
What is the formula for it?
Well, GPE = mgh.
So, when the height is the same in both cases, we know the gravitational potential energy is the same. Therefore, change in GPE = 0.
Sure, GPE did transform to KE during the swing, but all of that KE transformed back into the original amount of GPE.

Hope this helped! Please press “Thanks!”
