Resultant forces Flashcards
1
Q
What does it mean if an object is stationary?
A
The forces are balanced
2
Q
What does a resultant force mean?
A
a change in velocity and/or acceleration (a change in its state of rest or motion)
3
Q
If a car is driving forward with a force of 1000N and the air resistance is 600N, what will be the resultant force?
A
400N
4
Q
What is needed for an object to continue to move at a steady speed?
A
zero resultatant force
5
Q
What is the equation for the resultant force?
A
Resultant force = mass x acceleration (F=ma)
6
Q
What is the equation for acceleration?
A
Acceleration = resultant force/mass
