Momentum magnitude direction from "summary" of Force and Motion by Karen Kwitter,Steven Souza
Momentum is the combination of an object's mass and velocity, and is important when studying how an object in motion interacts with other objects. The magnitude of momentum is determined by an object's mass and speed, while the direction of momentum is determined by the direction of the object's motion.- Momentum is a measure of an object's motion, and it refers to the product of its mass and velocity. It has both magnitude (the distance an object is moving. and direction (the direction in which it is moving..
- Momentum determines how difficult it is to stop the movement of an object - the greater the momentum, the harder it is to slow or stop the object.
- Momentum can also be transferred from one object to another when they interact. For example, when a soccer ball is kicked, momentum from the player transfers to the ball and causes it to move.
- When two objects collide, the force each object experiences depends on the momentum magnitude and direction of the other object.
- Momentum can also be redirected by external forces such as tension force, friction, gravity, and air resistance.
- Conservation of momentum states that the total momentum of objects before and after a collision will stay the same.
- Objects with more mass have much more momentum than objects with less mass even if they are traveling at the same speed.
- A net force produces acceleration, which results in an increase in the object’s momentum.
- When an object is accelerating, its momentum increases as its velocity increases. Therefore, if it is traveling in the same direction, it's momentum will increase with time.
- Momentum can also act as a source of energy when it interacts with different types of surrounding media. This can include energy transfer in the form of sound waves, light waves, etc.
