What is Momentum?
The momentum of a body is the product of the mass of a body and its linear velocity. The symbol that is used to represent momentum is p .
Momentum, p = mass (m) × velocity (v)
p = kg × ms-1 .
Its unit is kgms-1 . It is a vector quantityVector quantities are quantities with magnitude and direction. Examples of vector quantities include displacement, velocity, position, force, and torque. More.
The momentum of a body depends on the mass and the velocity with which the body is moving. Its direction is the same as the direction of the object's velocity.
A bus can have a large momentum even if it's moving slowly because of its large mass .
A bullet can have a large momentum even though it has a small mass because it's moving with a high velocity.
If an object is at rest it has no momentum no matter how large its mass is.
In this case mass × 0 velocity = 0 Momentum
Note: If you want it in terms of Newton it becomes ‘Newton second (Ns)’.
Here is why;
Force = mass × acceleration (a)
Unit of acceleration = m/s2
