Question

When Jane drives to work she always places her pocketbook on the passengers seat.By the time she gets to work her pocketbook has fallen on the floor in front of the passenger seat. One day she asks you to explain why this happens in terms of physical science. what do you say? (use newtons laws to explain it)

Answer 1

The first law of newton says that if an object is at rest, it will keep at rest unless there is force acting on them. In the same way, if an object is in movement, it will keep in movement unless there is a force action on them.

The pocketbook of Jane is moving with the car, when she stops, the pocketbook keeps moving forward, so it falls on the floor because there is nothing that avoid its movement.
