According to Newton's 2nd Law, if you keep force constant, your acceleration will increase if you do what to the mass? 

Decrease it

400

A person walks 2 m/s North. Is this an example of speed or velocity? 

Velocity 
500

What is the different between mass and weight? 

Mass is a measure of an object's inertia, and weight is the force of gravity that an object experiences 

500

Slamming on your breaks so quickly that everyone in the car gets forced forward is an example of which law?

Newton's 1st Law

500

If you know both the speed and direction of an object, then you know its: 

Velocity

If there is a force that is pulling an object with 10 N to the left, and another force pulls the same object 10 N to the right, then we can say what about the forces? 

They are balanced
