Flashcards in Forces and Acceleration Deck (10):
All objects need a [ ] to start moving
If the [ ] force on a stationary object is zero...
The object will remain stationary
No resultant force = no change in [ ]
If there is no resultant force on a moving object...
it'll just carry on moving at the same velocity
When something is moving at a constant velocity then the forces must be ...
If there is a non-zero resultant force...
then the object will accelerate in the direction of the force
What 5 forms can 'acceleration' take as a result of a resultant force?
Speeding up, Slowing down
If there is a resultant force, on a diagram the arrows will be [ ]
What is the equation for acceleration? What does each bit mean? Units?
a = F/m
a = acceleration (m/s²)
F = Resultant force (Newtons N)
m = Mass (kg)
