Resultant forces

?
what is resultant force?
Th overall force on a point or object
1 of 15
In most real situations there are?
atleast forces acting on an object along any direction
2 of 15
The overall effect of these forces will decide?
the motion of the object-whether it will accelerate , decelerate or stay at a steady speed
3 of 15
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 forces has the same effect on the motion as the original forces acting all on it together)
4 of 15
If the forces all act along the same line the overall effect is found by?
just adding or subtracting them
5 of 15
The overall force you get is?
resultant force
6 of 15
For example?
stationery teapot all forces balance
7 of 15
The force of gravity is acting?
downwards
8 of 15
This causes a?
resultant force from the surface pushing up on the object
9 of 15
This is the only way it can?
balance
10 of 15
What would happen if there was no reaction force?
it would accelerate downwards due to the pull of gravity
11 of 15
the resultant force on the teapot is?
zero: 10N-10N=0
12 of 15
A resultant force means?
a change in velocity
13 of 15
If there is a resultant force acting on an object the the object will?
change its state of rest or motion
14 of 15
This causes?
change in the objects velocity
