Rising of smoke is an example of what type of motion according to Aristotle?
natural
normal
reaction
violent
What will happen if an external force is acted upon a body at rest?
it will move
it will not move
nothing will happen
it will remain in motion
What will happen to the acceleration of the body if a marble moves in a sloped downward plane?
accelerates
decelerates

not determined
Which of the following is NOT considered part of Aristotelian’s natural motion?
A book resting on top of a table
Pushing a cart
An apple falling from a tree
Smoke naturally rises
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.
What is the velocity and acceleration at a maximum height of an object thrown vertically upward
velocity = zero, acceleration = -g
velocity ≠ 0, acceleration = -g
velocity = 0, acceleration = g
both velocity and acceleration = 0
The grater the mass of an object, __________.
the more balanced it is
the greater its inertia
the more space it takes up
the easier it is to be moved
What is Newton’s second law of motion?
Law of inertia
Law of acceleration
Law of interaction
Law of conservation
Which of the following real-life examples demonstrates Aristotle's concept of natural motion?
Throwing ball into the air.
Pushing a heavy object on a surface.
Rowing a boat against the current.
A stone freely falling to the ground.
A book rests on a horizontal table. If the action force is the force that the table exerts on the book, what is the reaction force?
An upward force of exerted by the book on Earth.
A downward force exerted by Earth on the book.
An upward force exerted by the book on the table.
A downward force exerted by the book on the table.
Which material(s) will reach the ground first if they were dropped simultaneously in vacuum?
10-kg stone
20-g feather
15-g metal
all of the above
On which quantity does the acceleration of any free-falling object depend?
inertia
location
mass
speed
The law of conservation of energy states that
energy cannot be used faster than it is created
the total amount of energy in the universe is constant
the supply of energy is limited so it must be conserved
energy must be conserved; you are breaking a law if you waste it
Uniform motion in a straight line has always zero acceleration
TRUE
FALSE
According to Aristotle, force is necessary to sustain horizontal motion
TRUE
FALSE
Inertia refers to the ability of a body to resist change in motion.
TRUE
FALSE

Project
Projectile
Target
Trajectory
What is the shape of the trajectory of a projectile?
Circular
Elliptical
Hyperbolic
Parabolic
Acceleration is constant in bodies in uniformly accelerated motion.
TRUE
FALSE
In UAM velocity changes but at a constant rate.
TRUE
FALSE
