The famous scientist Galileo Galilei did several experiments with sloping
planes, which he rolled metal balls down so that he could study motion, By
changing the slope, he could study how the speed at which the ball rolled
was affected.
w What was the dependent variable in Galileo's experiment?
O A) the speed of the ball
OB) the slope of the plane
OC) whether the ball moved
OD) what the ball was made of

Tides that occur during the new and full moons
