# Topic 1.2 - Resultant Forces

?
What happens when two objects interact?
The forces they exert on one another are equal and opposite.
1 of 8
What is the resultant force?
A single force that has the same effect on the motion of an object as the original forces all acting together
2 of 8
What may a resultant force cause?
A change in an object's state of rest or motion
3 of 8
What happens if the resultant force acting on a stationary object is 0?
The object will remain stationary
4 of 8
What happens if the resultant force acting on a stationary object is not 0?
The object will accelerate in the direction of the resultant force
5 of 8
What happens if the resultant force acting on a moving object is 0?
The object will continue to move at the same speed and in the same direction
6 of 8
What happens if the resultant force acting on a moving object is not 0?
The object will accelerate in the direction of the resultant force
7 of 8
What is the relationship between force, mass and acceleration?
Force = Mass x Acceleration
