Biomechanics - linear motion Flashcards
1
Q
Define scalar
A
magnitude
2
Q
Define vector
A
magnitude and direction
3
Q
Is speed a scalar or vector?
A
scalar
4
Q
Is velocity a scalar or vector?
A
vector
5
Q
How many constant acceleration questions are there?
A
4
6
Q
What does SUVAT stand for?
A
s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = change in time
7
Q
List the 4 acceleration equations
A
v = u + at
v2 = u2 + 2as
s = ut + 1/2at2
s = 1/2(u + v)t
8
Q
What is newtons law?
A
equations of uniformly accelerated motion
