Question

What are real life applications of impulsive force?

Answer 1

Impulse is any force which acts for a very small amount of time. A few examples -

1. Most famous and commonly quoted - Batsman hitting the ball while playing cricket. The bat is in contact with the ball for very less time but changes its course quite significantly.
2. Kick starting a bike. The kick rod applies force for a very small time during which a dynamo is rotated and a small spark is produced to start the IC engine.
3. Similar to the first one - Whle playing Carroms, the striker hits the coin for a very short time but sends it to the pocket.
4. Hitting a gong with the stick sets it ringing loudly.
