Newton’s Second Law of Motion

How does changing the mass of an object affect its acceleration?

• It depends on the shape of the object

• It increases acceleration

• It has no effect on acceleration

• It decreases acceleration

What is the unit of force according to Newton's second law?

• Kilograms

• Kilograms times meters per second squared

• Meters per second squared

• Newton

What is the SI unit of force?

• Meter

• Kilogram

• Newton

• Second

What is the force required to give a 1-kg mass an acceleration of 1 m/s^2?

• 1 N

• 3 N

• 4 N

• 2 N

How might you change the number of people to increase the sleigh’s acceleration?

• Change the type of people

• Keep the number of people the same

• Remove people

• Add more people

What is the formula for Newton’s second law that is written to solve for mass?

• Mass = Force / Acceleration

• Mass = Force + Acceleration

• Mass = Acceleration / Force

• Mass = Force * Acceleration

What is the unit of acceleration?

• Kilograms times meters per second squared

• Newton

• Meters per second squared

• Kilograms

What is the mass of the volleyball if it experiences a net force of 2 N and accelerates at 8 m/s^2?

• 0.25 kg

• 0.5 kg

• 2 kg

• 1 kg

How might you change the number of people to decrease the sleigh’s acceleration?

• Change the type of people

• Add more people

• Remove people

• Keep the number of people the same

What does Newton's second law state about the relationship between net force, mass, and acceleration?

• Net force = Mass / Acceleration

• Net force = Mass * Acceleration

• Net force = Mass - Acceleration

• Net force = Mass + Acceleration
