1. Momentum is a vector quantity: This means it has both magnitude (size) and direction. The direction of momentum is the same as the direction of motion of the object.
2. Momentum is conserved: This is a fundamental law of physics stating that the total momentum of a closed system (one that's not affected by external forces) remains constant. This means that even if objects collide and interact, the total momentum before the interaction is the same as the total momentum after the interaction.
3. Momentum depends on mass and velocity: The momentum of an object is calculated by multiplying its mass by its velocity. This means a more massive object or an object moving faster will have more momentum.
4. Momentum is related to force and impulse: The change in momentum of an object is equal to the impulse acting on it. Impulse is the product of force and the time over which the force acts.
5. Momentum is related to kinetic energy: Momentum and kinetic energy are closely related. The kinetic energy of an object is proportional to the square of its momentum.
Examples:
* A heavy truck moving slowly has more momentum than a small car moving quickly.
* When you throw a ball, the ball has momentum. When the ball hits a wall and bounces back, the momentum changes direction.
* In a collision, the total momentum of the objects before the collision is equal to the total momentum after the collision.
