Flashcards in Forces and Acceleration Deck (10):
1

All objects need a [ ] to start moving

Force

2

If the [ ] force on a stationary object is zero...

Resultant
The object will remain stationary

3

No resultant force = no change in [ ]

velocity

4

If there is no resultant force on a moving object...

it'll just carry on moving at the same velocity

5

When something is moving at a constant velocity then the forces must be ...

balanced

6

If there is a non-zero resultant force...

then the object will accelerate in the direction of the force

7

What 5 forms can 'acceleration' take as a result of a resultant force?

Starting, Stopping
Speeding up, Slowing down
Changing direction

8

If there is a resultant force, on a diagram the arrows will be [ ]

Unequal

9

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)

10

When two objects interact, the forces they exert on each other are [ ].

Equal and opposite.
