1A.3 Adding forces Flashcards
1
Q
what is a resultant force
A
it is a force that was all the individual effects of all the forces combined
2
Q
how can we find the magnitude of a resultant force that has two forces that are perpendicular to each other
A
by using Pythagoras theorem
3
Q
how can we find the direction of a resultant force that has two forces that are perpendicular to each other
A
by fining the magnitude then using trigonometry
4
Q
how can we find the resultant force to two forces that are not perpendicular
A
- by finding the angle outside the triangle then finding the angle inside the triangle then using trigonometry
- by using the parallelogram rule where we would draw two vectors parallel to each other coming from the same point then we would draw an arc using a Drawing Compass then draw a line starting from the point where the vectors came from to the ark
