$300 7.47x10-11

$400  

$400 80.0 -It can only have 2 sig figs in the answer

$500 List and describe the 4 steps in the scientific method

$500 - Problem Hypothesis Experiment Conclusion

$100 What is the heliocentric model?

$100 Sun centered universe

$200 I was born on the same day as Galileo passed away

$200 Sir Isaac Newton

$300 He was the first to provide conclusive proof through observation and experiment, that the sun was at the center of the universe not earth

$300 Galileo

$400 Describe the difference between Natural and Violent Motion according to Aristotle

$400 Natural – Object in it’s proper place. Straight up or down motion Violent – Caused by pushing or pulling forces

$500 Describe the Inclined Planes Experiment

$500 He noted that balls rolling down a hill picked up speed and ball rolling up a hill lost speed. From this he reasoned that balls rolling along a horizontal plane would neither speed up or slow down. The ball would finally come to a rest not because of its “nature” but because of friction.

100 What equation represents the equilibrium rule?

$100 ∑F = 0

200 Define Mechanical Equilibrium

$200 A state wherein no physical changes occur

300 What is a support force?

$300 The upward force that balances the weight of an object on a surface

$400 What is a vector

400 A vector is an arrow that represents the magnitude and direction of a quantity.

500 What is the difference between tension and weight?

$500 Tension providing a upward force Weight providing a downward force

$100 What other name is Newton’s 1st Law of Motion known as?

$100 Law of Inertia

$200 Define Inertia.

An objects tendency to stay In its current state of motion $200 An objects tendency to stay In its current state of motion

$300 Define Newton’s 1st Law of Motion

300 Every object continues in its state of rest, or of uniform motion in a straight line, unless acted on by a nonzero net force.

400 What is the SI Unit for Force?

$400 Newton

$500 Describe the difference between weight and mass

Weight is gravity’s pull on you Mass is the “stuff” your made of $500 Weight is gravity’s pull on you Mass is the “stuff” your made of

$100 Describe what motion is

that we describe relative to something else. $100 Motion is movement that we describe relative to something else.

$200 What is velocity?

$200 Velocity is how fast and in what direction it moves.

$300 What is free fall?

$300 An object moving under the influence of the gravitational force is said to be in free fall.

$400 In Free Fall… It takes 9 seconds for a ball to reach the ground. What is its speed on impact? Acceleration before impact? What is its total distance traveled (assuming that after falling 1 second the speed reading is 10m/s and the distance traveled is 5m - Equation given d=1/2gt2

$400 90m/s 405 m 10m/s2

$500 An object starting from rest gains a speed v=at when it undergoes uniform acceleration. The distance covered is d=1/2at2 It’s acceleration is 2m/s2 What is the distance traveled after 7 seconds

$500 98 meters
