motion Flashcards
1
Q
distance? (2)
A
total amount of ground covered
distance = speed x time
2
Q
displacement? (2)
A
distance from the origin to final destination (shortcut/ hypotenuse)
to work out displacement, you can use Pythagoras
3
Q
speed? (2)
A
rate something moves from one place to another
speed = distance / time
4
Q
velocity? (2)
A
speed in a given direction
velocity = displacement / time OR acceleration x time
5
Q
acceleration? (4)
A
rate at which something speeds up or slows down
speeds up = increasing acceleration
slows down = decreasing acceleration
acceleration = final velocity - initial velocity / timt
