Velocity And Acceleration Flashcards
What is speed?
How fast you are going without a direction specified
What does velocity measure?
How fast you are going with a direction specified
What does acceleration measure?
It measures how fast the velocity is changing
What is acceleration measured in?
M/S 2
Speed =
Distance / Time
Acceleration =
Change in velocity / time taken
What is speed and velocity measured in?
M/S , KM/H , MPH
What happens to an object is all the forces acting on it are balanced?
It will stay still, or if it is already moving it will carry on at the same velocity
What does there need to be acting on an object for a steady speed?
zero resultant force
What does a resultant force mean?
Acceleration
What will an unbalanced force always produce?
Acceleration-Deceleration
What forms can this acceleration take?
Starting, stopping, slowing down, speeding up, changing direction
Resultant force=
F=MA
What is the overall unbalanced force also known as?
Resultant force
What is a resultant force?
A single force that has the same effect on the object as all the individual forces added together
