Physics - Resultant Forces
- Resultant force
is the overall
forces on a
point or object
- There are at least two
forces acting on an object
along any direction
- The overall effect of these forces
will decided the motion of the
object
- Whether it will accelerate, decelerate or stay at a steady speed
- Whether it will accelerate, decelerate or stay at a steady speed
- If you have a number of forces acting at a single
point, you can replace them with a single force.
- So long as the single force has the same effect on
the motion as the original forces acting all together
- So long as the single force has the same effect on
the motion as the original forces acting all together
- If the forces all act along the
same line the overall effect is
found by adding or subtracting
them
- The overall force you get is
called the RESULTANT
FORCE
- A resultant force means a change in velocity
- If there is a resultant force
acting on an object, then the
object will change its state of
rest or motion
- If there is a resultant force
acting on an object, then the
object will change its state of
rest or motion
