non-uniform motion Flashcards
1
Q
what is acceleration?
A
a change in the motion of an object, which can be in speed or direction, therefore a change in velocity
2
Q
when does acceleration occur?
A
when the forces acting on an object are not balanced, resulting in a net force
3
Q
what direction is acceleration of an object in?
A
the direction of the net force
4
Q
how to calculate acceleration?
A
change in velocity = final velocity - initial velocity
