Study Notes
Momentum
- Momentum is calculated by multiplying an object's mass by its velocity.
- Momentum is a vector quantity, meaning it has both magnitude and direction.
Newton's Second Law and Momentum
- Newton's second law, expressed in terms of momentum, states that the net force acting on an object equals the rate of change of its momentum in the direction of the force.
Impulse
- Impulse is calculated by multiplying the net force acting on an object by the time the force acts.
Impulse-Momentum Theorem
- The impulse caused by a net force is equal to the change in momentum of the object.
Isolated System
- An isolated system experiences zero external force.
Principle of Conservation of Linear Momentum
- In an isolated system, the total linear momentum remains constant.
Elastic Collision
- In an elastic collision, both total linear momentum and total kinetic energy are conserved.
Inelastic Collision
- In an inelastic collision, kinetic energy is not conserved.
