Newton's 2nd Law of Motion - Friday Quizizz Recap: P1

What is the formula for the 2nd law of motion?

• a=lw

• F=m/a

• F=ma

Why is it harder to push a van filled with bowling balls than it is to push a van with basketballs?

• The mass of the car is greater than the mass of the basketballs
• The mass of the bowling balls is greater than the mass of the basketballs
• The van with the basketballs is bigger than the van with the bowling balls
• It should be equally as hard to push the two vans

What is Newton's 2nd Law?

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• F = ma

• Friction

• Car because it has more mass

• Lawnmower because it has less mass

• Car because it has less mass

• Lawnmower because it has more mass
