kinetic energy Flashcards
1
Q
what is kinetic energy?
A
kinetic energy is the energy stored by objects’ movement
2
Q
what is the equation to find kinetic energy?
A
kinetic energy = 0.5 x mass x velocity²
Ek = 0.5 mv²
3
Q
what is the equation to find mass from the equation to find kinetic energy?
A
mass = kinetic energy / 0.5 velocity²
m = Ek / 0.5 v²
4
Q
what is the equation to find velocity?
A
v = √Ek / (0.5m)
OR
v = distance / time
5
Q
what is kinetic energy measured in?
A
joules (J)
6
Q
what is mass measured in?
A
kilograms (kg)
7
Q
what is velocity measured in?
A
metres per second (m/s)
8
Q
what is distance measured in?
A
metres (m)
9
Q
what is time measured in?
A
seconds (s)
10
Q
what is the abbreviation used for kinetic energy in the equation only?
A
Ek
