Question 6

Why does a heavy truck require more force to accelerate than a small car?

Answer

Because it has more mass, requiring more force to achieve the same acceleration

Answer

Because it has less inertia

Answer

Because the Third Law does not apply to heavy vehicles

Answer

Because friction is absent for heavy vehicles
