Forces and Newton's Laws of Motion

It takes more force to accelerate the iron man on the left than the iron man on the right because the iron man on the left has more mass. This best describes

• Newton's first law, the law of inertia

• Newton's second law, the law of acceleration

• Newton's third law, the law of action reaction

• The law of universal gravitation

Newtons 3rd Law of Motion states:

• An object at rest will remain at rest unless acted upon by an outside force.

• For every action, there is an equal and opposite reaction

• The greater the mass of an object, the more force it will take to accelerate the object

What is the name of the units that we measure force in?

• Einsteins 

• Newtons

• Kg

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because

• the passenger has the inertia to keep moving forward

• the passenger is being pushed by the seats of the car

• the passenger is better able to stop themselves in this manner

• the passenger has an equal and opposite force supporting their weight
