History of Models of Motion
Copernicus proposed this new idea
What is the Earth and planets move around the sun?
The difference between scalar and vector quantites
What is scalar quantities have only a magnitude, while vector quantities include both a magnitude and a direction? (OH YEAH!!)
The average speed of a car that travels 150 meters in 5 seconds
What is 30 m/s?
This happens to an objects velocity during free fall
What is it increases at a constant rate?
The most commonly used frame of reference
What is the Earth?
One way Galileo's concept of motion differed from Aristotle's
What is Galileo believed that moving objects continued to move unless acted on by an outside force while Aristotle believed an outside force was necessary to keep them moving OR Galileo believed that all objects fell at the same rate if air resistance is ignored while Aristotle believed that heavier objects fell faster than lighter objects?
The total distance a jogger has traveled if they run 100 m west and then 100 m east
What is 200 m?
What is 0 m/s?
The acceleration due to gravity on earth
What is 9.81 m/s2 downward or -9.81 m/s2?
Something treated as stationary and used to judge the motion of other objects
What is the frame of reference?
The only force acting on an object in free fall
What is gravity?
The distance a ball travels before reaching its highest point if it is thrown upward with an initial velocity of 29.43 m/s
What is 44.1 m?
The area under a velocity-time graph represents this
What is displacement?
The acceleration of a car if its velocity increases from +15 m/s to +45 m/s in 6 seconds
What is +5 m/s2?
Displacement is this type of quantity
What is a vector?
According to Aristotle, this is required for an object to keep moving
What is a continuous force?
The displacement of a rock 4.00 seconds after it has fallen off a cliff, assuming it has not hit the ground yet
What is -78.5 m or 78.5 m down?
The main difference between speed and velocity
What is velocity is a vector and speed is a scalar?
The velocity of a rock 3.00 seconds after it has been dropped from a cliff
What is 29.4 m/s downward or -29.4 m/s?
The slope of a velocity-time graph represents this
What is acceleration?
Galileo concluded this about falling objects
What is all objects fall at the same rate regardless of mass?
The displacement of an object that has traveled 10 m east and 5 m west
What is 5 m to the east?
This is defined as the distance traveled divided by the time of travel
What is average speed?
The length of time it takes a ball that is thrown upward with an initial velocity of 29.43 m/s to reach its highest point
What is 3.00 s?
It is defined as the change of velocity with respect to time
What is acceleration?
