1
Q
how can velocity changes in an object be shown?
A
through a velocity time graph, the gradient of it is acceleration (as its change in velocity divide time)
2
Q
what is the equation for acceleration
A
final velocity - initial velocity divide time
3
Q
vector
A
have magnitude and direction
4
Q
scalar
A
magnitude no direction
5
Q
distance time graphs, how is the speed shown
A
the speed is the gradient of the line, to find the gradient it is vertical divide horizontal
6
Q
newton’s 1st law
A
a stationary object witch no resultant force will remain stationary, a moving object with no resultant for will continue moving at its current velocity
7
Q
newton’s 2nd law
A
f = m x a
