Quiz on Newton's Second Law of Motion

What does Newton's Second Law of Motion state about acceleration?

• Acceleration is directly proportional to mass.

• Acceleration is inversely proportional to force.

• Acceleration is independent of mass.

• Acceleration is directly proportional to force and inversely proportional to mass.

If a force of 100 N is applied to an object with a mass of 20 kg, what is the acceleration?

• 10 m/s²

• 2 m/s²

• 20 m/s²

• 5 m/s²

What unit is used to measure force?

• Meters per second squared (m/s²)

• Newtons (N)

• Kilograms (kg)

• Pascals (Pa)

In the context of Newton's Second Law, what happens when an unbalanced force acts on an object?

• The object remains at rest.

• The object's velocity decreases.

• The object accelerates in the direction of the force.

• The object's mass increases.

What is the formula for calculating force according to Newton's Second Law?

• F = m + a

• F = m / a

• F = m × a

• F = a / m

If a person has a mass of 60 kg and is accelerated at 4 m/s², what is the force applied?

• 15 N

• 2400 N

• 60 N

• 240 N

According to Newton's Second Law, what happens to acceleration if the mass of an object increases while the force remains constant?

• Acceleration decreases.

• Acceleration remains the same.

• Acceleration becomes zero.

• Acceleration increases.

What is the mass of an object if a force of 500 N is applied and it accelerates at 5 m/s²?

• 100 kg

• 25 kg

• 75 kg

• 50 kg
