P8.3 Resultant forces Flashcards
1
Q
What is the resultant force?
A
This is a single force that has the same effect as all the forces acting on the object?
2
Q
What happens if the resultant force is 0?
A
We say that the forces acting on the object are balanced
3
Q
What is Newton’s first law of motion?
A
States that if the forces acting on an object are balanced the resultant force on the object is zero and:
if the object is at rest it stays stationary
If the object is moving it keeps moving at the same speed and in the same direction
