Biomechanics - linear motion

Question 1

Define scalar

Answer 1

magnitude

Question 2

Define vector

Answer 2

magnitude and direction

Question 3

Is speed a scalar or vector?

Answer 3

scalar

Question 4

Is velocity a scalar or vector?

Answer 4

vector

Question 5

How many constant acceleration questions are there?

Answer 5

4

Question 6

What does SUVAT stand for?

Answer 6

s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = change in time

Question 7

List the 4 acceleration equations

Answer 7

v = u + at
v2 = u2 + 2as
s = ut + 1/2at2
s = 1/2(u + v)t

Question 8

What is newtons law?

Answer 8

equations of uniformly accelerated motion

Question 9

Answer 9

3

Question 10

What are the 3 factors that affect projectile range?

Answer 10

• release speed
• release angle
• release height

Question 11

What is the equation for linear momentum?

Answer 11

mass x velocity
