Laws/Rules
Newton's Third Law
When an object exerts force on another object, the second object exerts an equal and opposite force on the first.
Acceleration
a=(v2-v1)/t
Draw a Velocity graph with zero acceleration
It doesn't matter where the line is but the velocity should be completely horizontal.
True of False? The total distance can be greater than the magnitude of its displacement, but the magnitude of its displacement can never be greater than the distance.
True
How many Players?
This game can be played with 2+ players, individually or in teams.
Newton's first law
An object stays at motion or rest unless acted upon by an unbalanced force.
Fnet equation
F=ma
Make an acceleration Graph for the following:
A car has a constant velocity of 15 m/s for 10s, before slowing down to a stop in the next 5 seconds.
X-axis is time, Y-axis is acceleration
Zero acceleration for 10s, then negative acceleration for the next 5 seconds.
If two objects are dropped from a high point downward 1 second apart, how long apart do they land?
More than 1 second
Less than 1 Second
The same time-1 second
The same-1 second
Every question is worth 100-500 points. Contestants take turns to pick 1 of the 4 topics and then pick how many points they want it to be worth. Everyone answers and if you win you add the points to your score, and if you get it wrong you subtract the points from your score.
The accelerations are equal in magnitude.
Centripetal Velocity
v=(2*pi*r)/t
Force diagram for a block sliding on a friction-less horizontal surface being pushed in the positive direction.
Fn and Fg are equal, only horizontal force is towards the positive direction.
In the expression "from zero to sixty" in however many seconds. What characteristic of its motion is being described?
Displacement
Difference between real jeopardy?
There are longer questions and answers do not need to be phrased as a question like (what is earth). There is also no daily double or final jeopardy. Finally, there is only 4 topics to make a quicker game instead of 5.
Which is always greater, Kinetic or Static Friction?
Static Friction
Equation of Horizontal Motion
Δx=Vt
Draw the projectile motion visual that represents how the horizontal and vertical motion change for an object as it moves through the age.
A parabola with arrows moving up and down and to right.
The horizontal motion should be constant to the right
The vertical motion gets smaller as it goes up and bigger as it goes down.
If you are on a train travelling horizontally and luggage starts sliding toward the front of the train, how is the train moving? Slowing down, Speeding up, or changing direction?
Slowing Down
What do you win?
Nothing.
Definition of Inertia
The tendency of an object to resist changes in motion
Write 3 out of the 4 Kinematic equations
V=V0+at
Δx=1/2(V0+V1)t
Δx=Vt+1/2at^2
V^2=V0^2+2aΔx
Draw visual that shows where centripetal velocity, centripetal acceleration, and centripetal force are directed towards in circular motion
Velocity is tangent to circle, Force is directed towards the center, acceleration is directed towards the center with less magnitude than the force.
If a bucket is being lowered by a very light rope, with constant velocity, the tension in the rope is....Equal Greater or Less than the weight of the bucket.
Equal to the weight
How to answer?
Write down your answer on a piece of paper or whiteboard and once the time of about 1 minute is up you cannot change your answer.
