How do you find momentum in Class 9?
The initial and final momentum of the object will be, p1 = mu and p2 = mv respectively. The change in momentum = m × (v – u). Here a = [(v – u)t (v – u) t ] is the acceleration, which is the rate of change of velocity. The quantity, k is a constant of proportionality.
What is the formula of final momentum?
Calculate the momentum of the system before the collision. In this case, initial momentum is equal to 8 kg * 10 m/s + 4 kg * 0 m/s = 80 N·s . According to the law of conservation of momentum, total momentum must be conserved. The final momentum of the first object is equal to 8 kg * 4 m/s = 32 N·s .
What is momentum write the formula?
Momentum is the quantity of motion possessed by a moving body, measured as a product of its mass and velocity. its formula is given as, momentum (p) = mass(m) × velocity (v). So it’s S.I unit is = kg × m/s = kgm/s (kilogram meter per second).
What unit is momentum measured in?
momentum (p) is measured in kilogram metres per second (kg m/s) mass (m) is measured in kilograms (kg)
What is momentum and its SI unit?
The unit of momentum is the product of the units of mass and velocity. In SI units, if the mass is in kilograms and the velocity is in meters per second then the momentum is in kilogram meters per second (kg⋅m/s). Being a vector, momentum has magnitude and direction.
What is the SI unit of money?
US dollar
What is momentum and its unit?
If the mass of an object is m and it has a velocity v, then the momentum of the object is defined to be its mass multiplied by its velocity. momentum= mv. Momentum has both magnitude and direction and thus is a vector quantity. The units of momentum are kg m s−1 or newton seconds, N s.
What is SI unit of Monument?
Answer:kg.m/s.
How do you explain momentum?
Momentum can be defined as “mass in motion.” All objects have mass; so if an object is moving, then it has momentum – it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving.
What is momentum in one word answer?
Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving. An example of momentum is how quickly a car is moving down a hill.
What is momentum one word?
noun, plural mo·men·ta [moh-men-tuh], mo·men·tums. force or speed of movement; impetus, as of a physical object or course of events: The car gained momentum going downhill.
Which of the following is the correct description of momentum?
The correct ‘description of momentum’ is the product of mass and velocity. Explanation: Momentum can be stated as the ‘mass in the motion’. All of the objects have a mass.
Is momentum a conserved quantity?
Momentum is a conserved quantity; the momentum of an object is never changed. The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed; the more massive object will have the greatest momentum.
What is the momentum of a 5kg object?
In the question it is already given that the mass of the object is 5 kg and the velocity at which it is traveling is 1.2 m/s. So the momentum of the object is 6 Newton.
What will be the momentum of a stone having mass of 10 kg when it is thrown with a velocity of 2m s?
20 kg m/s
How is the law of conservation of momentum derived?
Derivation of Conservation of Momentum Applying Newton’s third law, these two impulsive forces are equal and opposite i.e. If the time of contact is t, the impulse of the force F21 is equal to the change in momentum of the first object. The impulse of force F12 is equal to the change in momentum of the second object.
What will be the momentum of a stone having mass of 20 kg when it is thrown with a velocity of 8m s?
Answer: The answer is 80 kgm/sec.
What will be the momentum of a body of mass m which is moving with a velocity v?
mv
What is the momentum of an object of mass m moving with a velocity V Class 9?
1/2 mv2.
