What will be the effect on the boy in the picture if the driver stops quickly?

Because of inertia he will remain in the same position.

He will be pushed back into the car seat.

He will move from one side of the car seat to the other.

He will move forward pressing against the seatbelt.

19.

Pushing a child on a swing is easier than pushing an adult on the same swing, because the adult has more inertia.

Newton's 1st Law

Newton's 2nd Law

Newton's 3rd Law

None of them

20.

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
