Given the free body diagram, what is the force due to gravity on this object?
What is 6N?
200
The force that always acts perpendicular to the surface it is resting on.
What is the normal force?
200
The coefficient of friction between a box and the factory floor will (increase/decrease/stay the same) when more mass is added to the box.
Stay the same

If you are on a planet where gravity is weaker, will your mass increase, decrease or stay the same?
What is stay the same?
300
This is the maximum velocity an object can go, and the object is no longer accelerating.
What is terminal velocity?
300
If forces are this, then the object would not experience a net force and would not move.
What are balanced forces?
300
A box is moving to the left. Friction is acting in what direction on the object?
to the right
300
This law states that for every action there is an equal and opposite reaction.
Newton's 3rd Law
300
If the force acting on an object doubles, the acceleration will...
What is double?
400
At terminal velocity, the force of gravity is equal to ____________________________ and the object can no longer accelerate.

10.2N
500
The force of friction between a box and the factory floor will (increase/decrease/stay the same) when more mass is added to the box.
Increase

It's mass.

Explain why a heavier team should beat a lighter team in a tug of war contest. DO NOT say that the heavier team is pulling the rope with more force... that would be incorrect.
more weight = higher normal force = higher friction. Each step the heavier team takes is with more force of friction from the ground.
