1
Q
Ehat is reusltant force
A
Overall force acting on an object,taking into account all the different forces acting on it
2
Q
What 2 properties affect resultant force
A
Speed,direction
3
Q
What is equilibrium
A
All forces acting on an object are balanced out
4
Q
Newton first law
A
A resultant force is required to change the motion of an object
Forces on an object are balanced the rsultanr force is 0
5
Q
Unbalanced forces
A
When reusltwnt force of sn object is not 0, the forces acting on object are not balanced. Movement of object depends on size and direction of resultant force
6
Q
If the resultwnr force of object is
A
0, the ibject stays at rest or at same soeed or direction
Greater than zero, speed or direction of object will change
