Galileo Galile
determined by the nature of the object and how much of the four classical elements it contains. Aristotle also believed that natural motion is affected by the mass of an object.
Natural motion
caused by external forces (a push or pull) applied to the object.
Violent motion
an object in its Proper Place would not move unless there was a violent motion that will cause it to move.
Imposed motion
an object with twice the mass of another object would fall to the ground twice as fast.
Falling body Hypothesis
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newtons's first law Of motion
the natural tendency of objects to resist ch in their state of motion. The first law of motion is also called as the
Inertia
a force that causes a change in motion of an object.
Unbalanced force
any Push or Pull
Force
do not cause change in motion
Balanced forces
are not equal and opposite
Unbalanced forces
when all the forces acting upon an object balance each other
Equilibrium
the force that opposes motion
Frictional force
there is a change in its velocity
Accelerating
the measure of how fast an object is moving in a particular direction
Velocity
the rate of change of velocity (m/s²)
Acceleration
a push or a pull, it is needed in order to accelerate an object
Force
the acceleration of an object is directly proportional to the amount of the applied force, but inversely proportional to the mass of the object
Law of Acceleration
the amount of force exerted by gravity on an object
Weight
the amount of material and the measure of inertia of an object
Mass
for every action, there is an equal and opposite reaction
Law of interaction
the motion of a body following a circular path
Circular motion
a specific type of circular motion in which the motion of a body following a circular path is at a constant speed
Uniform circular motion
a line in which rotation takes place
Axis
the spinning of an object on its axis
Rotation
the motion of an object on a circular path
Revolution
the net inward forces that act upon the object to direct its path to the center of rotation
Centripetal force
the number of rotations or revolutions per unit of time
Rotational speed
the speed of an object depending on the radial distance or the distance from the axis to the object
Tangential speed
the distance from the axis of rotation to the object that is rotating about it
Radius
the force applied to an object multiplied to the distance it covered
Work
English Physicist
James Prescott Joule
occurs when the direction of the applied force is the same as the direction of the movement of the object
Positive Work
occurs when the direction of the applied force and the direction of the movement of the object are opposite to each other
Negative Work
