PHYSICAL SCIENCE FINAL TERM REVIEW

What is the biggest difference between the Geocentric Model and the Heliocentric Model?

• the shape of the planets' orbits

• the movement of the moon

• the center of the solar system

• the movement of the sun

He was able to combine what he saw of the stars' movements with mathematics to predict the movement of the planets. In order to make his predictions true, he worked out that the planets must move in epicycles, smaller circles, and the Earth itself moved along an equant. None of this was true, but it made the math work for his predictions.

• Aristarchus

• Aristotle

• Galileo

• Ptolemy

How did Brahe contribute to the formulation of Kepler’s laws of planetary motion?

• Kepler’s laws of planetary motion are just modified versions of Brahe’s conclusions about the motion of the heavenly bodies.

• Brahe provided the mathematical insights to help Kepler analyze the data he collected about the motion of the heavenly bodies.

• It was Brahe’s extensive and accurate observations that serve as raw data for the formulation of Kepler’s laws of planetary motion.

• Brahe independently developed the same laws of planetary motion as that of Kepler’s and Brahe’s ideas helped Kepler improve his version of the laws of planetary motion.

Which form of motion always follows a curved path and requires an initial launch force that is greater than the force of gravity?

• Horizontal Motion

• Vertical Motion

• Projectile Motion

• Free-fall Motion

How will Galileo sustain the horizonal motion of a ball?

• By doing nothing at all.

• By constantly kicking the ball.

• By kicking the ball with tremendous force.

• By kicking the ball when it is about to stop.

Which motion is NOT accelerating?

• A falling fruit from a tree

• A bike slowing down in the intersection.

• A speeding bus in the highway.

• A ball continually rolling 5 m/s for 5 hours

A stone hits the ground before a flat sheet of paper because ___________.

• it is less massive

• it is more massive

• the acceleration of gravity is greater on the stone

• there is more air resistance against the flat paper

Based from Galileo, force is needed to ___________

• sustain the motion of the object

• change the speed of the object

• change the direction of the object

• oppose the motion of the object

In the graph, which CORRECTLY describes the motion of the object?

• The object is at rest

• The object is at zero acceleration

• The object is in constant acceleration.

• The object is in unconstant acceleration.

Which of the following is the best example of diffraction?

• Your voice echoing back when you shout into a canyon

• A prism breaking a beam of light into its component colors

• A straw appearing to bend when you place it in a glass of water

• The music on your stereo getting louder when you turn up the volume
