Mass
* Symbol: *m*
* Unit: kilogram (kg)
* Definition: Mass is a fundamental property of matter that represents its resistance to acceleration. It's essentially how much "stuff" an object is made of.
There's no specific formula for mass. You typically measure it directly using a scale or balance.
Momentum
* Symbol: *p*
* Unit: kilogram meters per second (kg m/s)
* Definition: Momentum is a measure of an object's motion. It takes into account both the object's mass and its velocity.
Formula for Momentum:
* p = mv
Where:
* *p* is the momentum
* *m* is the mass
* *v* is the velocity (speed and direction)
Key Points
* Mass is a scalar quantity: It has magnitude only.
* Momentum is a vector quantity: It has both magnitude and direction.
* Momentum is conserved: In a closed system, the total momentum before an interaction equals the total momentum after the interaction.
