A marble with a mass of 5 grams sits on a banana leaf 10 centimeters vertically above the table. The acceleration of gravity g of 980 cm/s².
_________ __________ Calculate the Gravitational Potential Energy of the marble.
_________ __________ At the bottom of the banana leaf the same marble is moving at a velocity of 100 cm/s. Calculate the Kinetic Energy of the marble.
______________ As a percentage of the original Gravitational Potential Energy, how much energy was lost to friction and other sources of energy loss?
Mathematical models
_____
Identify by the letter which of the mathematical relationships on the graph represents the time versus distance relationship for a RipStik moving at a constant linear velocity with no acceleration.
_____
Identify by the letter which of the mathematical relationships on the graph represents the time versus distance relationship for a ball falling under the constant acceleration of gravity g.
_____
Identify by the letter which of the mathematical relationships on the graph represents the height versus velocity relationship for a marble rolling from a height h down a banana leaf and onto a flat table.
The graph shows momentum data gathered by a student in physcial science.
Plot the data provided in the table on the graph below and draw a line through the points.
_________ __________ Calculate the slope of the line.
_________ __________ Determine the y-intercept of the line.
___________ Was momentum gained or lost?
___________ Toughie: How much momentum was gained or lost?
Gravitational Potential Energy GPE = mgh
acceleration of gravity g = 980 cm/s²
Kinetic Energy KE = ½mѵ²
momentum = mass m × velocity ѵ
