Define the Law of Conservation of Matter
Energy cannot be created or destroyed only transformed into another form of energy.
A ball rolls horizontally off a roof at a speed of 1.5 m/s. How high is the roof if the ball travels 3.0 m horizontally before hitting the ground?
Pick the equation that fits with this question
**Bonus points for the answers
deltay= 0.5*ay*t2
**Bonus: -19.6 m
Define Acceleration
The rate at which velocity changes

why did the chicken cross the road?
Aristotle: It is the nature of chickens to cross roads.
Issac Newton: Chickens at rest tend to stay at rest, chickens in motion tend to cross roads.
Albert Einstein: Whether the chicken crossed the road or the road moved beneath the chicken depends on your frame of reference.
Werner Heisenberg: We are not sure which side of the road the chicken was on, but it was moving very fast.
Wolfgang Pauli: There already was a chicken on this side of the road.
Define Velocity
Speed in a given direction
A ball rolls off of a roof that is 9.8 m tall with a horizontal speed of 1.0 m/s. How far will it travel horizontally before it lands?
**Bonus points for the correct equation
1.45 m
deltaY = 0.5*ay*t2
deltax= vix*t
Define Distance
Length of a traveled path
Convert this velocity graph to an acceleration graphÂ
May ___ be with you
___ = mass * acceleration
Define Kinetic Energy
Enery of Motion
Aman walks around a park by moving 75m north, 125 m east, and 25 m south. What is Aman's displacement?
about 21.80 m
Define Displacement
Distance and Direction of the straight-line path from the beginning or the end
Convert this position graph to a velocity graph
Me when the homework tells me to find the third time derivative of the position vector.
You're a jerk :/
Define Potential Energy
Stored Energy

Define Speed
Distance/Time
Aman kicked a rock horizontally from the edge of a cliff with a speed of 12.0 m/s. It hit the ground below after it traveled 30.0 horizontally. How long was it in the air?
**Bonus points for the height of the cliff
t = 2.5 seconds
**Bonus: 12.25 meters
