2. A force is an influence which tends to set
a stationary body in motion or which
tends to change the speed and direction
of a moving body or which tends to
change the shape of a body.

3. Contact force
Non-contact force
Balanced force
Unbalanced force

4. A force that can be applied only when it
is in contact with an object is called a
contact force.
Examples: muscular force, frictional
force.

6. A force that can be applied without any
contact between two bodies is called non-contact
force.
Examples: magnetic force, gravitational
force.

8. When a number of forces act on a body,
and the resultant of these forces is zero,
then the forces are said to be balanced.

10. When a number of forces act on a body,
and the resultant of forces is not zero,
then the forces are said to be unbalanced.
