Momentum is defined as the product of mass and velocity of a moving object. It is represented by p, and p = mv , where m and v are the mass and velocity of the moving body. Momentum is directly proportional to mass and velocity and increases whenever there is an increase in mass or velocity.
What is the formula of momentum in class 9th?
The initial and final momentum of the object will be, p 1 = mu and p 2 = 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.
How do you find the momentum?
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object . where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object’s mass and directly proportional to the object’s velocity.
What is momentum class 9th Ncert?
Momentum can be well defined as the measure of the kinetic energy of the object. In simple words, the momentum is the product of mass and velocity. Complete answer: ... Momentum is defined as the mass (m) times the velocity (v) . If an object is steady so its velocity is zero resulting in zero momentum.
What is momentum short answer?
Momentum, product of the mass of a particle and its velocity . Momentum is a vector quantity; i.e., it has both magnitude and direction. ... Conversely, the momentum of a particle is a measure of the time required for a constant force to bring it to rest.
What is the momentum unit?
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 units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s.
What is the momentum of an object?
Momentum is a characteristic of a moving object that is related to the mass and velocity of the object . The momentum of a moving object can be determined by multiplying the object’s mass by its velocity. Like velocity, acceleration, and force, momentum is described by both a direction and a strength.
What is Newton’s second law class 9?
Newton’s Second Law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of the force . ie., F=ma. Where F is the force applied, m is the mass of the body, and a, the acceleration produced.
What is acceleration for class 9th?
Acceleration: It is a measure of the change in the velocity of an object per unit time . Acceleration can be caused either by change in direction of motion or change in speed or both.
What are the two types of momentum?
There are two kinds of momentum, linear and angular . A spinning object has angular momentum; an object traveling with a velocity has linear momentum. For now, and throughout chapter 7, we’ll deal with linear momentum, and just refer to it as momentum, without the linear.
What is momentum one word?
1 : a property (see property sense 1a) of a moving body that the body has by virtue of its mass (see mass entry 2 sense 1c) and motion and that is equal to the product of the body’s mass and velocity broadly : a property of a moving body that determines the length of time required to bring it to rest when under the ...
What is momentum Class 9 in physics?
Momentum can be well defined as the measure of the kinetic energy of the object. In simple words, the momentum is the product of mass and velocity . Complete answer: ... Momentum is defined as the mass (m) times the velocity (v). If an object is steady so its velocity is zero resulting in zero momentum.
How do you explain momentum?
Momentum is a measurement of mass in motion. Any object that is moving has momentum. In physics, momentum of an object is equal to the mass times the velocity .
Is momentum a energy?
Momentum is momentum and energy is energy. Momentum is NOT a form of energy; it is simply a quantity which proves to be useful in the analysis of situations involving forces and impulses. ... If it is moving, then it has kinetic energy. And if an object has kinetic energy, then it definitely has mechanical energy.
How do we use momentum in everyday life?
– A karate player break a pile of tiles or a slab of ice with a single blow of his hand . This is because a karate player strikes the pile of tiles or the slab of ice with his hand very very fast. In doing so, the large momentum of the fast moving hand is reduced to zero in a very, very short time.
