A - Forces And Their Effects Flashcards
If the resultant force on a stationary object is zero, the object will remain…
Still/stationary
If there is no resultant force in a moving object it will…
Carry on moving at the same velocity.
Velocity means….
Speed
If there is a non-zero resultant force, then the object will…
Accelerate in the direction of the force
Resultant force is…
The total of all forces acting in the direction of travel
How do you work out the resultant force?
You take one away from the other
Terminal velocity is…

Reaction forces are always _______ and ______
Equal and opposite
What is terminal velocity?
The maximum speed a falling object can reach depending on its area and shape
Friction is always there to…
Slow things down
The overall time it takes to stop depends on ….
The speed your going
The total stopping difference is made up from two parts which are …
Thinking distance
Braking distance
Gravitational potential only occurs when there’s _____
