Extension Question for experiment 1
Using a ball with A different mask changed the _______ of the ball at the bottom of the ramp, which is the energy of the ball due to its motion. Instead of measuring energy directly, we measure and compared _____________ in order To compared The energy levels of two different balls at the bottom of the ramp.
Using a ball with a different mask changed the kinetic energy of the ball at the bottom of the ramp. Instead of measuring energy directly, we measure and compared the distance traveled by the ball in order to compare the energy levels of two different balls at the bottom of the ramp.
Using a ball with a different mask changed the speed of the ball at the bottom of the ramp, which is the energy of the ball due to its motion. Instead of measuring energy directly, we measure and compared the distances traveled by the two different balls at the bottom of the ramp in order to compare the energy levels of the two balls.
The missing word in the first statement is "velocity." Changing the mask of the ball will affect its velocity at the bottom of the ramp, which is a measure of its energy due to motion.
In the second statement, the missing words are "height" and "heights." Instead of directly measuring the energy levels, we measure and compare the heights at which the two different balls reach after rolling down the ramp. By comparing the heights, we can infer the relative energy levels of the two balls at the bottom of the ramp.
