SC 130 Physical Science median term • Name:
1. ______________________________ A box of soap is 9.6 cm long by 3.9 cm thick by 6.1 cm wide. Calculate the volume of the box, writing the answer including units and using the correct number of significant digits.
2. For question two, use the following data from trial four of the ball roll experiment. The ball is thrown at a time of zero seconds.
a. ___________________ Physically, what is the slope in the ball roll experiment?
b. ___________________ What are the units of slope in the ball roll experiment?
c. ___________________Given that distance = slope × time + intercept, predict the distance the ball would roll after ten seconds. [ Ten seconds after being thrown.]
d. ___________________ Given that distance = slope × time + intercept, predict the time for the ball above to travel 50 meters.
3.
Marble momentum questions.
a. ____________________ If two marbles collide with a line of five marbles on a ruler track, how many marbles are ejected and roll on off the track?
b. Why do you think the marbles know what to do?
c. Explain how the speed of the marbles colliding with a line of marbles on a marble track affects the speed of the marbles ejected from the line.
