consists of seven base units, with a number of other units derived from these foundations

use the centimeter, gram, and second as base units, with other values derived from those three basic units

an elegant decimal system, where units of like type were defined by the power of ten

a quantity fully described by both magnitude and direction

a quantity fully described by magnitude

a useful method for determining the result of adding two (and only two) vectors which make a right angle to each other

the vector sum of two or more vectors

the angle (θ) of the resultant with the x-axis can be found from the relation:

describes the motion of objects without explicit reference to any forces; describes how objects move

deals with forces and their effect on motion

branch of physics that deals with the motion of objects and the forces that change it

the condition in which two or more forces acting on an object produces no acceleration because they balance each other out

the displacement of an object in relation to objects that are considered to be stationary

refers to the total path length traversed in moving from location or point to another

change of position in a particular direction; how far out of place an object is

a scalar quantity which refers to how fast an object is moving

a vector quantity which refers to "the rate at which an object changes its position"

the result of any change in velocity

velocity is the rate of change of a‎. ͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟ with time while speed is the rate of change of b. ‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟‎͟ ͟ with time

the motion of a falling body under the influence of the Earth's gravity

a force that impedes motion

motion of a body along a curved path

the path followed by a projectile

illustrations exposing the external forces acting on a body that is isolated from the universe

the amount of matter in a body

the pull of earth in a body. derived by multiplying the mass by the gravitational force

exists whenever two bodies come in contact with each other; otherwise referred to as 'Normal Force'

occurs if there is no change in the motion of a body

occurs if there is a change in the motion of a body

occurs if there is no change in the motion of a body

tendency of an object to maintain their state of rest or uniform motion

exists when there is no resultant force acting on a body at about any given axis

exists when the body is at rest

exists when the body is moving at a constant speed along a straight path

the frictional force that opposes one body rolling over another owing to the constant deformation of the surfaces in contact

the property called viscosity of liquids and gases to offer resistance to objects moving through them

an object extended in space which does not change its size or shape when subjected to a force

the point of an object about which all gravitational torques cancel

the point of at which all the mass of an object or system may be considered to be concentrated

the study of forces acting on an object that is in equilibrium and at rest

the study of electrical and magnetic fields, which are two aspects of the same phenomenon

if the center of gravity is lowered by a small displacement or rotation, the object is then in unstable equilibrium

if a slight displacement raises the CG, the object is in unstable equilibrium

There can never be a force acting unless two bodies are involved, one exerting the force and the other on which it is exerted

the vector sum or resultant of all forces acting on an object or system is referred to as unbalanced forces

the resultant is the vector sum of two or more vectors

any measurement of position must be made with respect to a reference frame

a change in direction of motion results in an acceleration even if the speed didn't change

scalar is a quantity which refers to 'the rate at which an object changes its position'

contact force is also known as normal force

in CGS system, the unit of mass is one gram equal to 1/1000 kg, and the unit of acceleration is 1 m/s²

according to the first law of motion, the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass
