Resultant Forces

resultant forces

Gravity isn't the only force in town - there are other forces that you need to know about too.

resultant force is the overall force on an object

1) usually an object will have lots of forces acting on it.

2) the overall effect of these forces will decide the motion of the object (how it will move).

3) if the forces all act in a streight line in the same or the opposite direction, you can find the overall force on the object by just adding or subtracting them.

4) the overall force you get is called the resultant force.

example: stationary teapot - all forces balance

1) the force of gravity (or weight) is acting downwards on the teapot.

2) this causes a reaction force from the table's…
