3. Define linear momentum? State its Sl unit?
Answers
Answer:
Linear momentum (momentum for brevity) is defined as the product of a system's mass multiplied by its velocity. ... The SI unit for momentum is kg·m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.
Answer:
Definition
Linear momentum is defined as the product of a system’s mass multiplied by its velocity.
In symbols, linear momentum is expressed as
p=mv
Momentum is directly proportional to the object’s mass and also its velocity. Thus the greater an object’s mass or the greater its velocity, the greater its momentum. Momentum p is a vector having the same direction as the velocity v.
The SI unit for momentum is kg⋅m/s.
