Resultant Forces
- A stationary object remains stationary
if the sum of the forces acting upon it
(resultant force) is zero
- A moving object with a zero resultant force
keeps moving at the same speed and in the
same direction
- Acceleration depends on the force
applied to an object and the object's
mass
- Resultant Force - forced acting on an object (eg.
different strengths and directions). This single
force has the same effect on the object as all the
individual forces acting together
- Factos that affect the size of the acceleration
- Size of the force
- The bigger the force, the greater
the acceleration
- Doubling the size of the resultant
force, doubles the acceleration
- The bigger the force, the greater
the acceleration
- The mass
- A force on a large mass will accelerate
it less than the same force on a smaller
mass
- Doubling the mass, halves
the acceleration
- A force on a large mass will accelerate
it less than the same force on a smaller
mass
- a = F divided by m
- a = acceleration of the object in
meters per second squared (m/s2)
- F = resultant force in newtons (N)
- m = the mass of the object
in kilograms (kg)
- a = acceleration of the object in
meters per second squared (m/s2)
- Size of the force
- m = F divided by a
