Post Lesson Quiz- Newtonian Mechanics

An object will remain stationary or move with constant velocity unless a force acts upon it. This is Newton's

• 1st Law

• 2nd Law

• 3rd Law

• 4th Law

Force is proportional to acceleration when mass is constant. This can be written as

• F=ma

• m=Fa

For every action, there is an equal and opposite reaction. This is one way of describing Newton's.....

• 3rd Law

• 2nd Law

• 1st Law

• 4th Law

What is the force experienced by an object with a mass of 5kg and has an acceleration of 5m/s/s?

• 25N

• 25m/s

• 25kg
