Newtons & Force: Everyday forces
Define:

weight
 

normal force
 

static friction
 

kinetic friction
 

coefficient of friction
 

air resistance
 

What is the direction of friction?
 
 

Friction is a force, yet it does not ever cause anything to speed up. Explain.
 
 
 

In what direction is weight?
 
 

In what direction is the normal force?
 
 
 

If an object is on a level surface, what is its normal force?
 
 
 
 

What causes friction?
 
 

What is the equation for calculating the force of friction. Label each variable.
 
 
 

If an object is setting on an inclined ramp and is not moving, what can be said about the force of friction?
 
 
 

If an object is sliding down an inclined ramp at constant velocity, what can be said about the forces acting upon the object?
 
 
 

If an object is sliding down an inclined ramp and is accelerating, what can be said about the forces acting upon it?
