MOTION Flashcards
It is the change of position of an object with respect to time
MOTION
one of the pioneers in studying motion, particularly distinguished between natural and violent motion
Aristotle
is either straight up or down and happens spontaneously.
Smoke rising up and rocks falling down.
It happens without the need for external force.
Natural Motion
Refers to the action necessary to move things horizontally and necessitates external action, such as pushing or pulling, to occur.
is characterized by the presence of unbalanced forces and does not occur without intervention.
Violent Motion
An object needs to be pushed or pulled to maintain its motion.
Arrow or Bullet gun
requires a continuous application of force to sustain movement.
Horizontal Motion
An object is influenced by the downward force of gravity.
Projectile Motion
introduced a contrasting perspective on motion, particularly emphasizing vertical motion as natural motion.
Galileo
In the absence of a resistance, objects would fall not depending on their weight, but in the time of fall.
Vertical Motion
An object in motion will continue to be in motion if unobstructed
An external force is not necessary for it to maintain the motion
Objects in —– maintain their trajectory indefinitely unless obstructed by an external force.
This type of motion is characterized by its continuity and does not require ongoing force application.
Horizontal Motion
If the object encounters a resistive force from a fluid equal or greater than its weight, it will slow down and reach a uniform motion until it reaches the bottom and stops.
Vertical Motion
—– follow a curved path.
Galileo believed that —– —– should be understood by analyzing the horizontal and vertical components separately.
Projectile motion
—– believed that the motion of an object depends on the element that mainly composed it. In this way an object will always tend to return to its natural state based on its composition.
Aristotle
—— stated that all objects moved depending on the forces acting on it and established the idea that objects thrown on space will move downward caused by the gravitational pull acting on it.
Galileo
states that an object at rest will remain at rest, and an object in motion will continue in motion with the same velocity, unless acted upon by an unbalanced force.
Law of Inertia
is the resistance of an object to changes in its motion, is directly proportional to its mass.
Inertia
When an object is in motion, —– opposes its movement, causing it to slow down eventually.
friction
This means that the greater the force applied to an object, the greater its acceleration, and the greater its mass, the smaller its acceleration for a given force.
Law of Acceleration
——- is directly proportional to the force applied on an object and inversely proportional to the mass of an object.
Acceleration
measure of an object’s motion and is determined by its mass and velocity.
equals the product of an object’s mass and velocity
Objects with larger mass and velocity have greater momentum.
It is simply “mass in motion”.
Momentum
measure of an object’s motion and is determined by its mass and velocity.
Momentum
equals the product of an object’s mass and velocity
Momentum
4 cases of Momentum:
Large mass & large velocity
Large mass & less velocity
Less mass & large velocity
Less mass & less velocity
It is the force that acts in a particular time w/c causes the momentum of an object to change.
Impulse
is the change in momentum of an object resulting from the application of force over a certain period of time.
