b) VELOCITY
6) ACCELERATION
ulant
d) MOMENTUM​

Answer 1

Answer:

a) FORCE  : S.I. unit Newton or N

b) VELOCITY  : S.I. unit meter/second or m/s

6) ACCELERATION : S.I. unit meter / second square or m / s^2

d) MOMENTUM​ : gram meter/second or g.m/s

Answer 2

Correct Question:

Write the S.I. unit for the following physical quantities.

a) FORCE

b) VELOCITY

c) ACCELERATION

d) MOMENTUM

Answer:

a) Force :

• The S.I. unit of force is Newton (N)

b) Velocity:

• The S.I. unit of velocity is metre per second (m/s)

c) Acceleration :

• The S.I. unit of Acceleration is metre per second square (m/s²)

d) Momentum :

• The S.I. unit of Momentum is Kilogram metre per second (kg m/s) since momentum = mass x velocity that is, product of its mass and velocity.

Explanation:

What is force?

• The external cause which can move a stationary object (the state of rest) or which can change the state of motion of a moving object is called Force.

What is velocity?

• The velocity of a body is the distance travelled per second by the body in a specified direction.

What is Acceleration?

• Acceleration is the rate of change of velocity with time.

What is momentum?

• Momentum of a body is the product of its mass and velocity
