Newton's second law states that F = M A F=MA , so it takes less force to accelerate a person with less mass by the same amount.

Moderator note:

Does this depend on the velocity of the child or adult when you're pushing them?

@Challenger master, it depends on the amount of force applied by the adult while pushing the child which is on the swing..

I thought it was inertia.
