Physics
What are the two categories of Aristotle’s Motion?
Terrestrial and Celestial
A category of motion pertaining to any movement of any object on earth
Terrestrial
a movement of any object beyond earth
Celestial
What are the three classifications of Terrestrial motion?
Natural, Violent, Alteration
—– motion determined by the nature of the object’s composition (earth, fire, water, air)
Natural
—— motion happens when an object is acted upon by any external force.
Violent
—— refers to a type of motion that describes qualitative change. water turning into ice. Also known as chemical change
Alteration.
this type of motion refers to the daily rising and setting of the sun.
Diurnal motion
apparent shift in location of the stars
annual motion
It is the change in position of any mass with respect to time
Motion
Motion can be traced back by —– years ago by Aristotle
1000 years ago
Aristotle proposed that a moving object is influence by this force
Motive force
type of motion that involves an object being thrown or fired near Earth’s surface
Projectile Motion
Aristotle explained Projectile Motion through the concept of ——-
antiperistatis
It refers to the actual path travelled by an object
distance (d)
it indicated the length as a straight line from the initial to the final position of an object
displacement (d)
This measures the distance travelled by an object over time
Speed
it represents the ratio of displacement and time
velocity
it is a vector quantity that measures the rate of change of velocity
Acceleration
this is magnitude alone
Scalar quantity
magnitude and direction
Vector quantity
distance and speed are vector quantity. True or false?
False - it is a scalar quantity
displacement and velocity are vector quantities. True or False?
True
it shows how the speed of a moving object changes with time
Speed Time Graph
The three laws of motion are
Law of Inertia, Law of Acceleration, and Law of Interaction
This is the 2nd law of motion where the total force acting on an object is not zero.
Law of Acceleration
Law of acceleration is directly proportional to ——- and inversely proportional to —–
net force, mass
This is the 1st law of motion where it is the tendency of an object to resist change in its state of motion. An object at rest tends to remain at rest. An object in motion will remain in motion with constant velocity unless acted by an external force
Law of Inertia
3rd law of motion, there is an equal and opposite reaction
Law of Interaction or equal and opposite reaction
What is the formula of acceleration?
Fnet = ma
It is the universality of gravity. All objects attract each other with force of gravitational attraction
Newton’s Law of Universal Gravitation
What is the value of the constant proportionality of gravity
6.673 x 10^-11 N m^2/kg^2
What is the formula of force of gravitational attraction?
F = Gm1m2/r2
It states that the total amount of mass in a reactant is equal to the sum f the mass of the product
Law of Conservation of Mass
states that this cannot be created nor be destroyed, it will only transfer from one form to another form. The total amount of this in a closed system remain constant over time
Law of Conservation of Energy
It is the total potential energy and kinetic energy. Loss of kinetic energy is gain in potential energy
Law of Conservation of Mechanical Energy
It is moving object, increasing in speed
Kinetic Energy
Stored energy increase in elevation increase in potential energy
Potential Energy
It is mass in motion, when an object is moving then it has momentum
Conservation of Momentum
Momentum is conserve when the momentum before the collision is the same after the collision. True or False?
True
What are the types of Collision?
Elastic, Inelastic, Perfectly Inelastic
It moves with different velocities after collision, the total kinetic energy before and after collision remains unchanged
Elastic Collision
two objects deforms so that the objects move in the same direction but with different velocities after colliding.
Inelastic Collision
collision in which two objects stick together and move with the same velocity after colliding
Perfectly Inelastic
This is the formula for Perfectly Inelastic. m1xv1 + m2xv2 = m1xv1+m2xv2.
true or false?
False
The formula is
m1xv1 + m2xv2 = (m1 + m2)vf
This graph tells a lot about motion. Where time is on the x axis and distance is on the y axis. It tells how far an object has move
