State the principle of impulse and momentum. And clearly difference between impulse and impact
F(force)= dP/dt (rate of change of momentum)
So, F*dt(impulse)= dP (change in momentum in the small time dt)
If impact means force, then the force multiplied by the time duration it is applied on a body equals impulse.
The principle of impulse and momentum relates to how the momentum of an object changes when it experiences an external force. The momentum of an object is defined as the product of its mass and velocity. According to Newton's second law of motion, the net force acting on an object is equal to its rate of change of momentum.
The principle of impulse states that the change in momentum of an object is directly proportional to the impulse applied to it. Impulse is defined as the product of the force applied on an object and the time interval over which the force is applied. Mathematically, impulse can be expressed as:
Impulse = Force × Time
Now, coming to the difference between impulse and impact:
Impulse: Impulse is the product of force and the time interval over which it acts. It quantifies the change in momentum of an object resulting from a force acting on it for a certain period of time. Impulse can be positive, negative, or zero, depending on the direction and duration of the force applied.
Impact: Impact, on the other hand, refers to the collision or interaction between two objects. It is a transient event that occurs when objects come in contact with each other. Impact is characterized by a sudden exchange of forces, resulting in a change in momentum for both objects involved in the collision.
In summary, impulse measures the change in momentum of an object caused by a force acting over a specific time interval, while impact refers to the collision or interaction between objects resulting in a sudden exchange of forces.
