- Impulse is defined as the product of the average force applied and the time duration of its application, leading to a change in momentum.
- Increasing impulse can be achieved by either increasing the average force applied, extending the contact time, or both.
- There is a direct relationship between impulse and momentum as described by Newton's second law of motion.
- Momentum is a property of a moving object, calculated as the product of its mass and velocity.
- The momentum of an object determines the time it takes to stop when acted upon by a constant force.
The impulse occurs during the contact time F: average force applied during contact time. An average force is used because the force varies during contact time.
Impulse: the product of the average value of a force and the time during which it acts being a quantity equal to the change in momentum produced by a force. The greater the impulse the greater the effect on the motion of the object. Impulse may be increased by increasing the average applied force for a given contact time. By increasing the contact time for an applied force or both. There is a relation between impulse and momentum from Newton's 2 law of motion. Impulse and change in momentum: the impulse is equal to the change in momentum of the object.
Momentum is a property of a moving body that determines the lenght of time required to bring it to rest when under the action of a costant force. Result of multiplying mass of a body by its velocity.
