P2 - Forces & Acceleration Flashcards
1
Q
What will happen if the resultant force of an object is 0 and why?
A
There is no velocity change so it will remain stationary.
2
Q
What happens to velocity when the forces are balanced?
A
The velocity is constant.
3
Q
What happens when there is a non-zero resultant force?
A
Acceleration.
4
Q
What is the formula for resultant force?
A
F = m x a
5
Q
What unit is resultant force measured in?
A
Newtons (N).
6
Q
Describe the forces when two objects are interacting.
A
Equal & opposite.
7
Q
What happens when there are two objects of a different mass interacting?
A
Movement.
8
Q
Who created the Laws of Motion?
A
Isaac Newton.
