- Resultant Forces
- A stationary object remains stationary if the sum of the forces acting upon it - resultant force - is zero.
- If the resultant force acting on an object is not zero, a stationary object begins to accelerate in the same direction as the force.
- A moving object speeds up, slows down or changes direction.
- Acceleration depends on the force applied to an object and the object’s mass.
- If the resultant force acting on an object is not zero, a stationary object begins to accelerate in the same direction as the force.
- An object may have several different forces acting on it, which can have different strengths and directions. But they can be added together to give theresultant force.
- In a force diagram, the longer the arrow the bigger the force.
- A resultant force acting on an object may cause it to begin moving or to change its movement.
- This is a single force that has the same effect on the object as all the individual forces acting together.
- Non Zero Resultant Forces
- When all the forces are not balanced, the resultant force is not zero.
- In this case, an object accelerates in the direction of the resultant force.
- When all the forces are not balanced, the resultant force is not zero.
- F = m × a
- F = Resultant Force in Newtons
- M = Mass of object in kilograms
- A = Acceleration in meters per second squared
- A stationary object remains stationary if the sum of the forces acting upon it - resultant force - is zero.
