Question

Explain why a train is more difficult to stop than a car if both are moving at the same speed

Answer 1

Because the Mass of train is more than that of the car, when they are moving at the same speed the force required to stop the train is much more than compared to that of the car.

Answer 2

the work done by an object is dependent on the change of kinetic energy . as the mass of train is bigger so the work done is bigger that that of car
so u have to do more work . that's why it hard
