Question

5. Write any two difference between speed
6. An object having mass 10 kg, what will be the weight of the
object on earth surface.
7 Define linear momentum.​

Answer 1

Answer:

1. Speed is a scalar quantity and velocity is a vector. Speed only determines the magnitude that is how fast is a body moving whereas velocity determines the direction also that is in which direction the body is moving. Speed is the rate of change of distance whereas velocity is the rate of change of displacement.
2. The gravitational force on moon is one sixth of the gravitational force on earth. Hence if a body is weighting 10 kilo on moon, its weight on the earth will be 60 kilograms. Hence the correct answer to the given question is 60 kilograms.
3. In Newtonian mechanics, linear momentum, translational momentum, or simply momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.

Answer 2

Answer:

★hey★

here's your answer !!

.________________________________.

MASS.

1. It is the amount of Matter contained in any object.

2. Its S.I unit is kilogram (kg).

3. It can never be zero.

4. mass of any object is directly related with its inertia.

WEIGHT.

1. It is the force of gravity on the object.

2. Its S.I unit is Newton (N).

3. It may be zero ( in space ).

4. weight of any object is not directly related with its inertia.

Hope it helps !!
