Physical Science Quiz 7

It refers to a change in position of a body with respect to its surroundings in a given interval of time.

• Period

• Speed

• Velocity

• Motion

One of the parameters of motion, where it is defined as the rate at which velocity changes in time, in terms of both speed and direction.

• Acceleration

• Position

• Distance

• Velocity

How would you explain the idea of motion to a 5-year-old child?

• "Motion is when things go from one place to another. Like when your toy car rolls on the floor or when you jump and skip around."

• "Motion is like when your favorite toys move. Imagine your teddy bear sliding down a slide or your toy car zooming across the room."

• "Motion is when things don't stay still. Think about throwing a ball and watching it roll away, or when you dance and twirl in a circle."

• "Motion means objects changing position. It's like when you play catch, and the ball moves between you and your friend."

Which of the following activities is NOT considered as motion?

• Riding a bicycle along a straight path.

• Standing still while holding a book.

• Swinging back and forth on a swing.

• Running in a race to the finish line.

A car is initially at rest, then accelerates forward in a straight path and eventually comes to a stop. What types of motion does the car experience during this sequence?

• Circular motion only.

• Linear motion only.

• Oscillatory motion only.

• Both linear and oscillatory motion.

According to Aristotle, an object in horizontal motion requires a continuous force to stay in motion. In contrast, what does Galileo propose regarding the horizontal motion of objects?

• Objects in motion require a continuous force, similar to Aristotle's view.

• Objects in motion will eventually come to rest, as there is no inherent tendency for motion.

• Objects in motion will continue in motion unless acted upon by an external force.

• Objects in motion experience resistance proportional to their speed.

In Aristotle's view, how would he likely explain the motion of a falling object compared to Galileo's explanation?

• Aristotle explains that heavier objects tend to fall faster than lighter objects due to their elemental properties, while Galileo explain that all objects regardless of the weight, will fall in the rate, regardless of their mass.

• Aristotle and Galileo’s provided similar explanation about the concept vertical motion where all things fall at the same acceleration.

• Aristotle established the concept of free-falling object which explains that all terrestrial objects move at the same speed due to God as the prime mover, while Galileo explains that the heavier bodies tend to fall slower than the lighter bodies.

• Aristotle claims that all bodies that fall is due to the gravity, while Galileo claims that all things fall to the ground due to its nature as ground-type objects belongs to the ground.

In Aristotle's view, how would he likely explain projectile motion compared to Galileo's explanation?

• Aristotle and Galileo have the same concepts and view about projectile motion is a combination of uniform motion in the horizontal direction and uniformly accelerated motion in the vertical direction.

• Aristotle explains that projectile motion is due to the combination of horizontal motion of the object and the pull of earth’s gravity influence in vertical motion, while Galileo explains that projectile objects in motion is the result of the external force (impetus), as the impetus gradually losses it influence to the object, then the object will go free falling to the ground.

• Aristotle explains that will remain parallel to the ground as long as it still has external force within its body before falling back into the ground, while Galileo’s concept explains that objects in projectile motion is always influence not just one but two motion, horizontal and vertical.

• All of the choices are correct.

Speed is the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively short distance in a given amount of time.

• First statement is true, while second statement is false.

• First statement is false, while second statement is true.

• All statements are true.

• All statements are false.

A free falling object is an object that is falling under the sole influence of gravity. The law of Inertia explains that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

• First statement is true, while second statement is false.

• First statement is false, while second statement is true.

• All statements are true.

• All statements are false.
