forces - acceleration Flashcards
what does the acceleration of an object tell us
the change in its velocity over a given period of time
what does an upward sloping line tell us
an object is accelerating
what does a straight line tell us
the object is stationary
what does a downwards sloping line tell us
an object is decelerating
what does the total area under the graph tell us
the distance traveled in a specific direction
how do you work out the stance travelled if the acceleration or deceleration aren’t constant ( no straight lines)
count squares
total the parts of squares
true or false
if an object is accelerating at a constant rate, we can use a different equation
true
we would use:
v^2 x u^2 = 2as
what is the acceleration of an object when it is falling towards the surface of the earth
9.8 m/s^2
what is meant by the term terminal velocity
the maximum velocity that an object can attain when it is falling through a fluid, such as air or water
