Understanding Newton's Second Law

Who was Sir Isaac Newton?

• A French painter

• An American inventor

• An English mathematician and physicist

• A Roman emperor

What does Newton's Second Law state about acceleration and force?

• Acceleration is inversely proportional to the net force

• Acceleration is directly proportional to the net force

• Acceleration decreases as force increases

• They are unrelated

How does the mass of an object affect its acceleration according to Newton's Second Law?

• Greater mass leads to greater acceleration

• Mass has no effect on acceleration

• Acceleration increases as mass decreases

• Acceleration is directly proportional to mass

Which formula represents Newton's Second Law of Motion?

• Acceleration = mass / net force

• Mass = acceleration / net force

• Net force = mass * acceleration

• Acceleration = net force + mass

What does Newton's Second Law F=ma stand for?

• Force equals mass times acceleration

• Force equals mass plus acceleration

• Force equals mass minus acceleration

• Force equals mass divided by acceleration

• Because of opposing forces

• Lack of mass

• Insufficient force applied

In a system with two objects, when does the center of mass not move?

• When external force is applied

• When there is no net force

• When both objects have the same mass

• When the objects are stationary
