Study Notes
Momentum Definition
- Momentum is the product of an object's mass and velocity
- Represented by the symbol
pand measured in kg·m/s - Momentum is a vector quantity, meaning it has both magnitude and direction
Momentum Formula
-
p = m × v - Where
pis the momentum,mis the mass, andvis the velocity of the object
Characteristics of Momentum
- Momentum is a conserved quantity in closed systems, meaning it remains constant unless acted upon by an external force
- The more massive an object is, the more momentum it will have at a given velocity
- The faster an object is moving, the more momentum it will have at a given mass
Types of Momentum
- Linear Momentum: the product of an object's mass and velocity in a straight line
- Angular Momentum: the product of an object's moment of inertia, angular velocity, and radius from the axis of rotation
Momentum in Different Frames of Reference
- Galilean Relativity: momentum is not conserved when viewed from different inertial frames of reference
- Special Relativity: momentum is conserved when viewed from different inertial frames of reference, but the formula for relativistic momentum is different from the classical formula
Applications of Momentum
- Collision Physics: momentum is used to analyze and predict the outcomes of collisions between objects
- Rocket Propulsion: momentum is used to calculate the efficiency and efficiency of rocket propulsion systems
- Sports: momentum is used to analyze and improve athletic performance, particularly in sports involving collisions or rapid changes in direction
