Every object continues in a state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by forces exerted upon it. 1 st law - 200
Newton’s First Law 1 st law - 200
A measure of inertia 1 st law- 400
Mass 1 st law - 400
The force of gravity on an object 1 st law - 600
weight 1 st law - 600
A mother finds that her newborn infant sons weighs 300N, a possible new world record, calculate the boys mass. 1 st law - $800
b8a 30.6 kg (30 kg okay) 1 st law - 800
When you compress a junked car into a cube, which will change, its mass, volume, or weight? 1 st law
volume 1 st law
The acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as the net force, and is inversely proportional to the mass of the object 2 nd law - $200
Newton’s Second Law 2 nd law - $200
Sketch and find the resultant of a 6-N force going left and a 8-N force going up. 2 nd law - $400
6-N 8-N 10-N
Calculate the acceleration of a 2000 kg single-engine airplane just before takeoff when the thrust of its engine is 500N. 2 nd law - $600
0.25 m/s 2 2 nd law - $600
A rocket fired from its launching pad not only picks up speed but also accelerates as it goes up, why? (HINT: about 90% of the mass initially in a rocket is fuel) 2 nd law - $800
Its mass decreases as fuel is used up. Therefore, the same force will accelerate it more. 2 nd law - $800
A certain force applied to a 2kg mass accelerates the mass at 3 m/s 2. How much acceleration will the same force produce on a 4 kg mass? 2 nd law - $1000
1.5 m/s 2 2 nd aw - $1000
d2 Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object. 3 rd law - $200
Newton’s Third Law 3 rd law- - $200
When swimming, you push the water backward- call this the action force. What is the reaction force? 3 rd law- - $400
The water pushing you forward. 3 rd law- - $400
Daily Double Make a Wager
3 rd law- The Daily Double Why can you exert greater force on the pedals of a bicycle if you pull up on the handlebars?
Because the handlebars push down on you, and in turn, the pedals 3 rd law- Daily Double
If action equals reaction, why isn’t Earth pulled into orbit around a communication satellite? 3 rd law- - $800
Because of Earth’s much greater mass and inertia 3 rd law- - $800
3 rd law- - $1000 If a bicycle and a massive truck have a head on collision, upon which vehicle is the greater impact force? Which vehicle undergoes the greater change in motion?
The forces are equal but the bicycle experiences a greater change in motion 3 rd law- - $1000
1 kilogram time a meter per second squared is also equal to this unit potpourri- $200
Newton potpourri- - $200
The combination of all forces acting on an object potpourri- $400

the ratio of the force of kinetic friction to the normal force potpourri- - $600
Coefficient of kinetic friction potpourri- $600
A bowling ball and a baseball are both dropped from the top of a third floor apartment window, which will hit the ground first? Which has the greater force of gravity on it? potpourri- - $800
Both hit the ground at the same time but the Bowling ball has more force acting on it gravity
potpourri- - $1000 The force that opposes the movement of two surfaces that are in contact and are sliding over each other.
potpourri- - $1000 Kinetic friction
Final Jeopardy Category: The horse and his cart Make a Wager
Final Jeopardy A horse is pulling a cart along a path. How can the horse pull the cart if the forces between the two of them cancel out?
Final Jeopardy They will move if the force the horse pushes against the ground is greater than the force of friction
