To illustrate:
It means that the object keeps doing what it does. This tendency is called inertia.
Inertia is the tendency of an object to resist change in its state of motion. Galileo discovered
the concept of inertia in the seventeenth century. Based on his experiment, if there is no
inertia, an object will move in a constant speed.
Remember:
The bigger the object has a greater tendency to resist changes in its state of motion.
Between a golf ball and a bowling ball, a bowling ball is more difficult to move.
The motion of an object may be caused by two kinds of forces: Balanced and
unbalanced forces. The table below explains the two forces briefly.
BALANCED FORCE
UNBALANCED FORCE
- Equal in magnitude - Unequal in magnitude
- Opposite direction
- Can be the same or opposite
direction
- Causes no change in the
speed of the object
- Causes change in speed and
direction
- Net force is equal to zero - Net force is not equal to zero
