Read the questions carefully and choose the letter of the correct answer.
1. Galileo Galilei proposed an experiment where a ball rolled down in a U-shape incline. In
an ideal scenario, the ball would move along the incline until it returned to its original height.
Why will this not occur in reality?
The force of gravity prevents the ball from moving upward.
The friction between the ball and the incline reduces the ball’s energy.
The momentum of the ball increases as it moves, causing it to rise above its
original height.
The ball experiences a second collision with the incline, reducing its velocity.
__________ states that objects fall at a speed proportional to their weight and inversely
proportional to the density of the fluid they are immersed in.
Aristotle
Albert Einstein
Galileo Galilei
Isaac Newton
All of the statements regarding Newton’s first law of motion below are true except?
A baseball thrown in space will keep moving in the same direction until it hits something.
If I am riding a skateboard, it does not spontaneously reverse directions.
A ball rolling straight down a tilted plane hill will not veer left or right unless something
pushes it.
Dropping a box causes it to accelerate downwards.
Galileo Galilei’s and Newton’s law of inertia are very much alike. Which of the following is
the main difference of the two concepts?
acceleration
friction
force
gravity
What is the condition that must be followed to fulfill Newton’s first law of motion?
the force must increase constantly.
the force must decrease constantly.
the forces must be balance.
the forces must be unbalanced.
Describe how the concept of motion revolutionized from Aristotelian concept to the
concept of Newton’s first law of motion.
