What is the unit of mass?
A
kg
8
Q
What is velocity measured in?
What is the unit of velocity?
A
m/s (metres/seconds)
9
Q
How to you calculate kinetic energy?
A
Ek= ½XmXv²
10
Q
How do you calculate mass?
A
m= Ek
————
0.5Xv²
11
Q
How do you measure velocity?
A
v=√Ek/0.5Xm
OR
v²=Ek/0.5Xm
12
Q
What is velocity equal to?
A
velocity= distance
———-
time
