what is a momentum? write the units of it in SI & CGS system
Answers
Momentum is the product of the mass and velocity of a particle.
Its S.I unit is kg m/s and its CGS unit is g cm/s.
- Momentum is a word most often used in sports. When it is said that a team is strong it is difficult to beat a team. Momentum is a term associated with Physics and refers to the amount of movement contained in the body. When an object is moving it is said to be dynamic.
- In simple terms, momentum is defined as “mass movement”. All objects have a certain weight, and when an object is moving, it has a force, that is, its weight in movement. The intensity of an object depends on two parameters, firstly the size of the object and secondly the speed of the object. So the pressure depends on the weight and speed of the object.
Answer:
Momentum is the product of mass and velocity.
Explanation:
The quantity of the motion of the body is called Momentum.
There are three types of momentum - linear momentum, translational momentum and simple momentum.
It is denoted by "p".
It depends on velocity, direction of the motion of the body.
It is a vector quantity, that possesses a magnitude and a direction.
Momentum = Mass X Velocity.
p = m × v
SI unit of momentum is Kg.m.s⁻, this is equal to newton-second.
CGS unit of momentum is g.cm.s⁻¹.
According to Newton's second law of motion: change in body's momentum is equal to the net force acting on it.
Hence, Momentum is a speed gained by a moving object.
