Motion

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

• Vertical Motion

• Projectile Motion

• Free fall Motion

• Horizontal Motion

13.    What motion does Galileo pertain, if there is no interference, a body in motion will keep moving in a straight line forever?

• Vertical Motion

• Projectile Motion

• Free fall Motion

• Horizontal Motion

13.    Which of the following is TRUE about natural motion and violent motion?

• Natural motion needs an external force to move while Violent motion return to its violent states based on the body’s composition.

• Natural motion return to its natural states based on the body’s composition while Violent motion needs an extra force for it to move.

• Natural motion is also a Horizontal motion.

• Violent motion is also a Vertical motion.

13.    This is the idea used by Aristotle to explain how objects sustain their horizontal motion.

• Antiperistasis

• Natural motion

• Violent motion

• Projectile motion

Which experiment is used by Galileo Galilei to prove uniform acceleration?

• Collision Experiment and Projectile Experiment

• Cannonball Experiment and Projectile Experiment

• Plane Experiment and Cannonball Experiment

• Force Experiment and Electromagnetic Experiment

 

18.    Which is TRUE about Galileo’s cannon ball experiment?

•  

  When objects are dropped simultaneously at the same height, they will reach the ground at the same time.

• When an object has twice mass as much as another, they will reach the ground at the same time.

• When an object with a different mass is dropped simultaneously at the same height, they will not reach the ground at the same time.

• When an object is dropped simultaneously with different height, they will not reach the ground.

19.    Which of the following is TRUE about Galileo’s assertion about free - falling?

bodies?

• Bodies will fall on the surface of the Earth at a constant acceleration.

• Bodies will fall on the surface of the Earth at a constant speed.

• Bodies will fall on the surface of the Earth at a constant velocity

• Bodies will fall on the surface of the Earth at a constant projectile

20.    Which of the following is NOT an assertion of Galileo?

• A body that is in uniform motion will move a distance that is proportional to the time it will take to travel.

• A uniformly accelerating body will travel at a speed proportional to time.

• An object in motion will keep moving; and the external force is not necessary to maintain the motion.

• A body will fall on the surface of the Earth at a constant speed.

21.    What will happen to the acceleration of the body if a marble moves in a

sloped downward plane?

 

• accelerates

• decelerates

• nothing

• stays the same

22.    Which observation and conclusion is NOT included to the plane experiment and cannonball experiment of Galileo Galilei?

• A body moving down an inclined plane increases its acceleration by the same value after every second.

• The maximum acceleration of a body is attained when the inclined plane is positioned vertically as if the body is falling.

• The bodies fall with constant acceleration on the surface and that gravity pulling all bodies downward is a constant force.

• The body or object that falls has a constant gravity acceleration.
