Study Notes
- The change in momentum mentioned is in the x-direction and its value is -5√2 units.
- The change in momentum should be written as -5Δp in vector form because it is in the x-direction.
- The rate of change of momentum of an object is directly proportional to the applied external force acting on it.
- Newton's Second Law states that the rate of change of momentum of an object is directly proportional to the applied external force.
- If the external force applied on an object changes, its momentum will also change accordingly.
- In the SI units, the value in SI units is equal to 1 unit.
- In non-Newtonian physics, where the object is moving very fast, the concept of mass changing is considered.
- Conservation of momentum states that if the external force is zero, the rate of change of momentum will also be zero.
- In the case of a ball being caught, when the hand brings the ball backward, the time interval is forcibly increased, causing the force to decrease.
- The use of springs and shocks in cars is an example of utilizing the concept of increasing time interval to reduce force during sudden impacts.
