Understanding Newton's Second Law

What does Newton's Second Law state about the relationship between force, mass, and acceleration?

• Force is the sum of mass and acceleration.

• Acceleration is dependent on the mass of the object and the force applied.

• Force is independent of mass and acceleration.

• Mass is dependent on the force and acceleration.

What is the SI unit of force and how is it defined?

• Joule, defined as one kilogram times one meter per second squared.

• Pascal, defined as one kilogram times one meter per second squared.

• Watt, defined as one kilogram times one meter per second squared.

• Newton, defined as one kilogram times one meter per second squared.

Using the triangle method, how do you calculate force if mass and acceleration are known?

• Divide mass by acceleration.

• Multiply mass by acceleration.

• Subtract acceleration from mass.

• Add mass and acceleration.

If a 5000 kg car needs to accelerate at 20 m/s², what force is required?

• 50,000 Newtons

• 100,000 Newtons

• 10,000 Newtons

• 200,000 Newtons

Which object will accelerate faster if both are given the same force, one with more mass or one with less mass?

• It depends on the shape of the object.

• Both will accelerate at the same rate.

• The object with less mass.

• The object with more mass.
