Enumerate at least 3 activities in real life situation which involves the concept of momentum and impulse.
Answer (1)
Answer:1. Car Crash: When a car crashes, the momentum of the car is significantly reduced in a very short time. This rapid change in momentum is an impulse. The greater the impulse (and thus the force involved), the greater the damage to the car and potential harm to the occupants. Safety features like airbags and crumple zones are designed to increase the time over which the impulse occurs, thereby reducing the force. 2. Hitting a Baseball: When a baseball bat strikes a ball, the bat delivers an impulse to the ball. This impulse changes the ball's momentum, sending it flying. The force exerted by the bat and the time of contact both affect the magnitude of the impulse and the resulting speed of the ball. A solid hit involves a larger impulse, resulting in a faster ball. 3. Walking: Each step you take involves a change in momentum. Your leg moves forward with momentum, and when it impacts the ground, an impulse occurs. This impulse causes a change in momentum, bringing your leg to a stop and transferring momentum to your body, propelling you forward. The repetitive cycle of these impulses allows you to walk.
