define mass and momentum in 13 lines
Answers
Answer:
1.mass
a large body of matter with no definite shape.
2.Momentum
the quantity of motion of a moving body, measured as a product of its mass and velocity.
Answer:
A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter. Mass is commonly measured by how much something weighs.In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. ... The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity. The units for momentum would be mass units times velocity units.We can define mass as the inherent property of matter. It is the measure of the inertia of a body, mass tells us how much matter there is in a body, we can measure the mass of a body on earth by measuring the force of gravity acting on it, the SI unit of mass is kilogram (kg).
Remember mass is not the same as weight, even though we measure the mass of a body by measuring its weight, a body with the same mass weighs differently on the moon than it weighs here on earth, mass is one property of matter that doesn’t change easily.We can define momentum as the quantity of motion of the body. It is measured by mass×velocity, as momentum depends upon velocity, and it depends on the direction of the motion of the body as well.
Momentum = Mass X Velocity
p = mv
The S.I. unit of momentum is kilogram metre per second(kgms−1)
