what are the two states of motion
Answers
Two different state of motion are
State of motion
===========
When position of body changes with time
E.g.A bus moving on road is in state of motion as its position changes with time.
State of rest
=========
A vehicle standing on the road is in state of rest.
However, the state of motion and state of rest is all relative . A person sitting in the moving bus will be in state of motion in reference to a person standing on the road while it is in state of the rest relative to the bus driver .
State of Motion
Newton's First Law
Inertia and Mass
State of Motion
Balanced and Unbalanced Forces
Inertia is the tendency of an object to resist changes in its state of motion. But what is meant by the phrase state of motion? The state of motion of an object is defined by its velocity - the speed with a direction. Thus, inertia could be redefined as follows:
Inertia: tendency of an object to resist changes in its velocity.
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion(i.e., velocity) unless acted upon by an unbalanced force. An object in motion with a velocity of 2 m/s, East will (in the absence of an unbalanced force) remain in motion with a velocity of 2 m/s, East. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity.
As learned in an earlier unit, an object that is not changing its velocity is said to have an acceleration of 0 m/s/s. Thus, we could provide an alternative means of defining inertia:
Inertia: tendency of an object to resist acceleration.
