Flashcards
Forces and Acceleration
Flashcards do conjunto (9)
- 1What does an object need to start moving?A force
- 2What happens when the resultant force on an object remains zero?The object will remain stationary
- 3What does 'no change in Velocity' mean?That there is no resultant force
- 4What happens if there is no resultant force on a moving object?It'll carry on moving at the same velocity
- 5What are the criteria for an object to move at a constant velocity?All forces on the object must be balanced
- 6What must an object have to keep it moving at a steady speed?Zero resultant forces
- 7What happens when there is a non-zero resultant force on a moving object?It will accelerate in the direction of the least amount of force
- 8What will a non-zero resultant force always produce?Acceleration (or deceleration)
- 9List five different forms of acceleration.1) Starting
2) Stopping
3) Speeding up
4) Slowing down
5) Change in direction
