Newton III

Newton's ​ (a)   Law states that objects in motion tend to stay in motion, and objects at rest tend to stay at rest unless acted upon by an outside force.

• First

• Second

• Third

Answer explanation

This is the "I'm Chillin" Law, objects will continue to do whatever they are currently doing until they are forced to stop or do something else.

The girl on the sled will remain in motion unless

• her motion is changed by magnetic forces.

• she is stopped by an outside force.

• she accelerates at a constant speed.

• the force of friction forcer her to move faster.

A car is driving at a constant velocity of 75 m/s on the highway headed to Tucson, on a windy day. What is the force acting upon it to continue it's state of motion?

• 0 N, due to "the constant velocity" which means the car is already moving. It does not need force to continue it's state of motion.

• Really? This question again? Obviously it is 75 m/s because of one of Newton's Laws.

• Wait, I do know, I just don't know how to explain it. But, It is one of the laws... right?

• 75 N to the right, due to action and reaction, as well as inertia.

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
