Momentum Units: Measurement in kg*m/s

In summary, momentum is a measure of an object's motion that takes into account its mass and velocity. It is measured in units of kilogram-meters per second and is important in physics as a conserved quantity. Unlike velocity, which is a measure of speed and direction, momentum also considers an object's mass. It can also be negative in certain scenarios.

would you give a measurement of mometum units? like kg*m/s?

Of course momentum has units! And you are exactly correct, one such unit would be kg*m/s.
 
  • #3
It's also N*s. (Newton * Second)
 
  • #4
N*s is usually used as the unit for impulse. But the two units are fundamentally equivalent, and only a real stickler would complain about their cross-usage.

You stickler.
 

FAQ: Momentum Units: Measurement in kg*m/s

What is momentum?

Momentum is a measure of an object's motion, taking into account its mass and velocity. It is defined as the product of an object's mass and its velocity.

How is momentum measured?

Momentum is measured in units of kilogram-meters per second (kg*m/s). This unit is derived from the product of the base units of mass (kilograms) and velocity (meters per second).

Why is momentum important in physics?

Momentum is important in physics because it is a conserved quantity, meaning that it remains constant in a closed system. This allows us to make predictions about the motion of objects and understand how forces act on them.

How does momentum differ from velocity?

Momentum and velocity are related but distinct concepts. Velocity is a measure of an object's speed and direction, while momentum also takes into account the object's mass. An object can have the same velocity as another, but its momentum will differ if its mass is different.

Can momentum be negative?

Yes, momentum can be negative. This occurs when an object is moving in the opposite direction of its defined positive direction, or when its velocity is negative.
