Flashcards in Forces and Acceleration Deck (14):
Who worked out the Laws of Motion? and when?
Isaac Newton in the 1660s.
An object needs what to start moving?
A resultant force.
If the resultant force on a stationary object is zero what will the object be doing?
Object will remain stationary.
What does no resultant force mean?
No change in velocity .
If there is no resultant force on a moving object what will happen to the object?
Carry on moving at the same velocity.
If a train/car/bus is moving at a constant velocity then what must the forces be?
Forces must be all balanced.
To keep going at a steady speed what must there be>
Zero resultant force.
What does a resultant force mean?
If there is a non-zero resultant force what will happen to the object?
It will accelerate in the direction of the force.
A non-zero resultant force will always produce what?
The "acceleration" can take 5 different forms
What are they?
When an object is accelerating what will the arrows be like?
If there's an overall force it will always...
