Laws of Motions
Newton's First Law
Newton's First Law states that an object at rest or moving
uniformly with constant speed or direction will continue to
remain at rest or move uniformly unless acted upon by an
unbalanced force. If the net force is zero, the velocity will
remain constant.
An unbalanced force can change the object's speed, direction,
or both. A balanced force means that all the forces cancel each
other out, resulting in equilibrium. If the forces do not cancel
each other out, there is no equilibrium, and the net force is not
zero.
Understanding Balanced and Unbalanced
Forces
A balanced force means all the forces cancel each other out,
resulting in equilibrium.
An unbalanced force means the net force is not zero,
resulting in no equilibrium.
If the forces acting on a body result in some change, they are
unbalanced.
An object in equilibrium stays in equilibrium only if the net
force is zero.
An object in equilibrium will not always stay in equilibrium.
Understanding Inertia and Force
When a car turns, every object inside it has a tendency to
move in the direction and speed it was moving previously. The
passengers have a tendency to move outwards, but it's not due
to a force acting on them. In fact, there is no force pushing
them outwards, it's just their tendency to maintain their
motion. This tendency is called inertia and is measured in
terms of mass. The more mass an object has, the more
resistance it has to change its motion.
