100
force that opposes the sliding motion of two surfaces that are touching each other

Graph the story
Jane walked really slow to the grocery store that was 4 km from her house. She stopped at the store to pick up a couple items, then she continued on her way to Shelby's house that was 2 km beyond the grocery store.

Calculate the velocity of Sara who ran north during her jog of 6 km and finished with a time 32 minutes
What is 0.1875 km/min North?
200
This law explains how a really large object must to pushed or pulled with a large force to get it to accelerate as quickly as an object with a small mass.
What is Newton's 2nd law or Law of Acceleration?
200
this is the rate in change of velocity
What is acceleration?
300
The SI unit for force
What is the Newton?

Graph this situation
A racecar starts from rest and speeds up to 40 km/hr in 5 seconds and then continues at the same speed for 10 seconds, until slowing back down to 0 km/hr at a constant rate.

Calculate the acceleration of a ball rolling down a hill for 5.9 seconds that has a final velocity of 34 m/s
What is 5.76 m/s/s down?
300
This is the tendency of an object to resist change in motion
What is inertia?
300
This type of friction can be felt as an object is falling through the atmosphere
What is fluid friction?
400
The unit for acceleration
What is m/s/s or m/s2?
400
Graph this situation
A runner starts out at a slow jog, then gradually speeds up and reaches his runner's high so he stops accelerating to reach his maximum speed for the remainder of his run

Calculate the force on an object that must be applied to a 4 kg object to roll with an acceleration of 3 m/s/s
What is 12 N?
400
As the mass of an object doubles, while keeping the force the same, the acceleration of the object will do this
What is be cut in half?
400
This is the strongest type of friction to overcome
What is static friction?
500
The SI unit for momentum
What is kg X m/s/s
or
g X m/s/s

Mary accelerates very quickly on the track, reaches her top speed for a while, then gradually slows down to a stop.
What is look at board?

When two forces are equal pushing on an object but acting in opposite directions, the net force would be this
What is zero or balanced?
500
This is the maximum speed an object can reach while in free fall
