Kinematics
It is the study of motion of objects without considering the forces acting on them.
Statics
The study of objects at rest
Dynamics
It is the study of cause of motion.
Rate
anything divided by time
displacement
the shortest straight distance between the two points, having a particular direction. Or the change in position of the body.
distance
It is the length of the path (curved/line) described by an object moving in space.
Velocity
the rate of change of displacement
.
uniform velocity
the velocity which does not change in magnitude and direction.
Speed
the magnitude of velocity is called speed or the rate of change of distance
Acceleration
the rate of change of velocity .
Uniform acceleration
when the change in velocity is constant in equal intervals of time.
Gravity
It is the force by virtue of which the earth attracts the bodies towards its centre.
Acceleration due to gravity
It is the acceleration in free fall bodies by gravity.
Newton's First Law of Motion
is states that "A body continues its state of rest or iuniform unless an external force acts on it. "
Inertia
It is the property of matter by virtue of which it opposed any change in its state of rest or that of motion.
Force
It is the agency that causes or tries to change the state of rest or that of the motion of the body.
Newton's second law of motion
According to its "When an unbalanced force acts on aa body it produces acceleration in the body in the direction of force which is directly propotional to the force and indirectly propotionaal to the mass of the body"
Newton's third law of motion
It states that "Every action has an equal and opposite reaction"
Weight
the gravitational pull of the earth on the body
tension
When an object is suspended by a sstring the force that acts along the string and is equal in magnitude and opposite in direction to the weight.
thrust
A forcefully pushing force
up thrust
It is the force that pushes things up in water.
Reaction
The opposing force of action (which is the application of force)
Friction
The resistive or opposing force to the motion of the object generated when the two surfaces or in contact.
Work
Work is said to be done on a body if it attains some displacement with the application of force.
Conservative field
A field is said to be conservative if work is independent of the path followed and the net work done in a closed path is zero.
Power
the rate od doing work OR work done per unit time.
Energy
the ability or capacity to do work.
Kinetic energy
the energy possessed by a body when it is in motion
Potential energy
the energy possessed by a body when it is at rest or hanged or due its position .
law of conservation of energy
is states that "the energy neither can be created nor destroyed."
